REASON always crashing on me, help!

Archived from groups: rec.audio.tech (More info?)

I have been running reason 2.5 for ages now, but recently, every time
I try to make a track, within a minute or two the cpu meter crawls up
until I get the 'computer too slow to play song' message, so not
exactly crashing, but it shouldn't be doing that and never did on my
system, and I of course hafto stop and restart. I tried defragging
and reinstalling and restarting of course, but still same problem, and
I never had it before. is it possible this has to do with sp2?
whatever it is, aid me please!
thanks,
chris jongkind
