Made a nice track, then suddenly X1C made everything go downhill

I saved often. Then my computer crashed (not related to sonar). Rebooted, reloaded the track and now all groove clips are playing much faster than before, also the overall sound has changed, seems like one of the plugins stopped working, some eq or so. Sigh. That's X1C for ya right there.

Hi my similar experience:
I have a laptop and my Main Studio is a desk top ...my laptop will do minimal edit work but is working up to "b" upon installing "c" on my 'guinea pig' laptop..I opened a project and all is well and when I hit control s....I had a blue screen of death...never before a very nice laptop...it recovered (it actualy said "blue screen" as the issue) my computer started with an error 0xc000000e and said to get my install disk it was missing components ..I hit start as normal or something and it did boot....now this happened 2 more times...and all seems well...it hasn't happened again...but am I ever nervous to put this on my main DAW.
