I have had the BI Tools 2 installed for a while now, over a year probably, and I have had this problem at least 3 or 4 times.
At complete random, my P drive will no longer exist on my computer after a PC restart. I didn't uninstall any of the tools, or even mess with any files associated with them. One of the times, I just started my PC, my P drive was just fine and all I did was go browse the internet then shut down my PC. The next time I turned on my computer, the P drive was gone. Everything is backed up in another folder luckily, but I need the P drive and its a total pain when it just uninstalls it self like this. A few buddies of mine have also had this problem on at least one occasion and don't know why either.
Anybody know why this is happening and if there's anything I can do to avoid it?
