Just to add a possibility, the one time I was having random Hoster crashes (about 3 years ago), I thought it was a bug in the program. It was shutting down when it wanted to - no rhyme nor reason, could never duplicate the problem, some nights would go fluidly with not even a skip, other nights it would crash - sometimes more than one time, turns out I not only had a bad hard drive, but my mother board was dying as well. I replaced both and never had a problem since. Never would've thought it was a hardware problem since the computer was not even a year old at the time.
Seems many of the posts here are describing exactly what I went through. May want to have the computer itself checked out, might not be Hoster at all!
Just replaced the MB on my home computer last week as well, although it wasn't Hoster that I was running into problems with - it was everything.
