MC5 and JamStix2 -

This weekend I installed JamStix2 (full version) and tried it in MC5.  The installation went fine, and the soft synth loads correctly into a project.  I fooled around a bit with a previous song project, muting the drums kit I had and allowing JamStix2 to jam along, and also picked through various options or presets.  I was surprised that I couldn't find anything that was even close to the groove I was after, and it looks like to use it I'd have to do a lot of manual editing.   However that's not the reason for the post - 
 
after I had left it alone for a few minutes while reading some of the docs on it, my system crashed.  Or more accurately, it crashed my MC5 - it closed out gracefully at least, and my Windows OS was fine - I took the precaution of shutting the PC down, then bringing it all back up again clean.  This time (and every time now subsequent), as my MC5 loads I get a popup that says that I need to run the JamStix2 updater.  What's that and where is it run from, anybody know? 
 
After I clear the message, MC5 runs OK, but I don't know if it's really running stable.  I do not have the demo version installed under it, this is the full product.  Aside from the initial install and the download of the default kit, I think that's all I've done.  Appreciate any tips from those of you who use it.  This is the 2nd attempt I've made to install it since I bought it many months ago when I ran MC4, because I had a lot of problems with it initially too, so decided to stay away from it.  I've since reloaded/reinstalled the OS (Win XP Pro Sp3) with MC5 so it's a clean installation.  Thanks for any tips.  

Be sure you go to your Jamstix page and see if there are updates you need. I do not remember the latest release number but it you're getting a notice.... I'd at least check it out.

The system should be running stable... the pop up window is just a notice.... and you could ignore it forever if you wanted.

Crashes and memory dumps.... I have accepted them as "par for the course" with windows based recording. Back up and save often. Reboot when necessary.

Many thanks, guys.  I haven't taken time to go to the site yet (gotta find my registration info), but I do know that there's several updates that have come out since I bought the ver 2.0, I think there's 2.5.2  so I'll go through all that first.  I'll check back and post results, thanks again!
