I have just manually uninstalled an earlier version of v9 (build 2250 - per an earlier procedure for manually uninstalling - maybe the early procedure doesn't work with v9 ?) and reinstalled build 2323. Now I get a BSOD when rebooting. I can get around this by rebooting into an earlier copy of XP before the install but this defeats the purpose of trying to run build 2323. So I fixed a different problem by updating to 2323 but am no better off. Perhaps I should wait for a later build hopefully with an uninstall included. I cannot go back to V8 because it doesn't support my new hardware. Nor do earlier versions of V9. I am fighting against having to reinstall XP but it looks like a loosing battle. My personal feeling is that XP reaches a certain point with new program loads etc and then starts to give trouble hence the need for a rebuild. My rebuilds take over 20 hours of work and in this case I have no way of reinstalling any earlier backups because none of them will work with my new hardware (Silicon Image addon Raid controller). Or is there a fix for the BSOD ?
