I've been using uTorrent since it first came out in the beta days and I've loved the product ever since, its amazing. However, I just recently update my PC to Vista Ultimate x64 SP1. However, I seem to be having trouble on a certain download. Currently I'm downloading file A and B and seeding file C. If I download File B it works perfectly If I try both A and B it crashes, if I try A alone it also crashes. So I've narrowed it down to File A being the culprit. I really don't want to have to look for a new file similar to A so I set up mt Processor to do that Affinity thing, however this file is kind of large so changing the affinity is kind of annoying. is there anything I can do to fix this? I have all the .dmp files if you need to see them. **update I was going through the setup guide just to make sure I was doing everything correct. I started downloading the test torrent only to have it crash just a minute later. it was going good until It crashed.even with the affinity set. could it be that now i have 6 gig of mem instead of 2 like before? ** I reinstalled utorrent and everything seemed to work. I left it over night downloading and when I woke up around 7 it had crashed and only gone to about 15% completion. Can some one help me please? I'm connected through my linksys wrt 54g router to my comcast voip cable modedm.
