Hogwarden, Thanks for a great product! I've been having some problems that I need assistance with. I have PBooost 1.3, but recently reformated my primary harddrive, re-installing Windows XP. PBooost 1.3 was on my secondary harddrive and subsequently, was never removed. I downloaded the 1.4 package on my user account screen here at Renderosity, and installed it onto my secondary harddrive. Problem is, it locks up. I've uninstalled 1.3 and 1.4 (1.3 registry entries would have been wiped out in the reformat anyway.) Re-installed 1.4, still locks up. Uninstalled it again, then started over by installing 1.3, then 1.4. Still locks up. 1.3 worked like a champ, so I'm probably missing some key component here. Right now, just so you know what's up, 1.3 is completely removed from my system, and I've got a fresh install of 1.4. I've removed all the '##switchBank' folders...thinking something was up there. All to no avail. Running P4, WinXP NTFS.
