What version are you running now? You might want to try running the 32bit version...if you are not having memory issues in BI3 there is no benefit in running 64bit...otherwise if you insist on 64bit and you are having crashes you need to email support because most of the crashes have been resolved. You should include information on the error code you get or info in event viewer.i have same issue, i upgraded to 4 and had nothingbut crashing issuse, i start it up go to bed iwake up its crashes in the night and its random times, i restart it and go to work and same thing i come home it has crashed, wth i pay for this i had to go back to 3 and run it so far not one crash and its been running 7days 18hrs 13min 7sec not one brain fart, what is wrong with B.I.4 ??
