If ungrouping with TI-Connect fails, you can always try with SourceCoder too, altough when ungrouping, I don't know if SC lets you save your program in 8xp form.

Be carefull with grouptool, I once had it corrupt an entire group of Serenity progress with token FF
From my experience, DO NOT use Group Tool.  The one time I used it, it killed my calc as I did a Mem Clear to fix my problem.  It really messed with the VAT and other stuff. :(

The worst GroupTool has done to my calc is reset my lower case flag.

But I didn't use it that much, because I found with the 83+'s limited memory it was easier to back stuff up on my computer than create groups.

GroupTool never caused me any trouble. but, it seems that Celtic III has made it obsolete.

Do you mean that the calc cursor got locked down to lowercase ALPHA, not letting you turning it off? I remember back in the days it happened to some people at school and I always wondered how to fix it without forcing a RAM clear

No, I mean the system flag that defines whether lower case is on or off was reset, disabling lower case on the calculator. It can easily be reset using CalcSys or an assembly program that changes the flag- it was just annoying to have to do each time I used GroupTool.

Oh ok. At least I am glad it is not what I said. That one was annoying because you couldn't access most menus anymore since it wouldn't let you go out of ALPHA mode anymore

* calcdude goes searching for the right flag combos that cause this :P (lol j/k)
That must be annoying, DJ. Anyway, I don't see why GroupTool would reset that flag... weird. (I can see TI doing it, but not the author, who I cannot remember)

I actually did that once on purpose on my own calculator (probably stupid of me). I think it was fixed simply by pulling a battery out, though.

Late reaction @DJ: It's possible to fix ERR:VERSION problems with calcsys in normal programs, not in groups. There is a byte in the VAT (I refer to day 21 of asmin28 days, since I don't remember the offset), that is called the version byte and it is never used. Sometimes, it ends up as $ff. You simply have to correct it to a zero, and then everything should work fine (transferring etc.).

Aaaah ok I see. Unfortunately the only ERR:VERSIONs I ever got were in groups, though, so it wouldn't help me much if it happened :(

Thanks, though.

so I hear that you can reset bits (make them 0) on the archive, does this mean you could set the byte FF to 00 and fix it?

How are groups stored on the calculator anyway? 28D seemed to skip right past them :P

I was the one that wrote GroupTool, many years ago. It's poorly coded and if I had the time, I'd rewrite it. It probably sets or resets that lowercase flag without regard to whatever it was before launching it.

Groups are complicated to explain (it's also been a really long time since I looked at them). If I remember correctly, they're a series of VAT entries and variable data, one after the other. You'd just have to pick one apart and look at it in a hex editor.
