Upgrade Serial Number

As of Feb 2023, Upgrading your SN is no longer supported by eSellerate Please skip to this article instead.

The Serial Number Manager / eCommerce company "eSellerate" has pulled the plug on us, and I have no choice in the matter. The only thing you can do now to rectify the situation is purchase a new license using the latest version of kJams.

I am terribly sorry about all this, I held on as long as possible to the ability to convert an old SN to a new one (about five years).

If it makes you feel any better, I did work on the 64bit kJams for over five full years without really getting paid for it, since i made it a free update, so your patronage really helps.

If you're upset by having to pay again, I understand, please contact me and we'll see what we can do. Please mention that you read this message.

If, however, you have sympathy for a poor software engineer who's labor of love doesn't even pay the bills, and you have some disposable income, please consider subscribing to me on Patreon, to help offset the expenses of keeping the kJams doors open.

Old News No Longer Relevant

In 2017, in anticipation of moving to a 64bit platform, kJams transitioned from the old serial number type (provided by eCommerce company "eSellerate"), to the new serial number type (provided by "Paddle").

"eSellerate" is 32bit-only, while "Paddle" could be run in 32 or 64bit. In other words, the old serial number works only on 32bit computers, while the new SN works in either type.

What that means is, ONLY the old, 32bit version of kJams (using the new Paddle) is capable of converting the old SN to the new SN, since it can use both systems.

So if you are now using the 64bit version of kJams, but you ONLY have an old (32bit) serial number, you're in a bit of a bind.

On Windows the solution is easy: run the current 32bit version of kJams (latest update), and convert your SN from 32 to 64. Then you can use your new SN in the 64bit version of kJams.

On Mac, it's a bit harder: you may not have access to the old, 32bit operating system any more (Mojave). You'll have to find an old mac that runs Mojave, or find a Windows computer, to convert your old SN to the new SN format, which you can then use in kJams.

How to convert an older serial number

1. run the LATEST version of kJams (32bit) on a computer that supports it. Doesn't matter which type, mac or windows (even if your goal is to eventually use mac)
2. enter your serial number
3. kjams will walk you through upgrading the serial number to the new type
4. when that is complete, you'll get an email with your new SN, and kJams will be activated
5. if you're then going to move to a different computer:
   1. in kJams, go to the menu bar and pick Help->Deactivate, which will deactivate your new SN

Now you can run kJams (64bit) and enter the new serial number.

Maybe I had already converted?

If you think you may have already converted your license, then try this:

1. run kjams
2. in the menu bar, pick "Help->Recover License…"
3. ensure that the email address you used for your license is correct, hit OK

If all goes well, you will get an email with your serial number in it.

What if I can't convert the old one?

If you can't find or get to a computer that can run the 32bit version of kJams, the only way out is to just purchase kJams again. Sorry about that. (But I do thank you, i've literally been working for five years to port kJams to 64bit)
