I don't know where I got the idea that you needed to uninstall before doing an upgrade. I checked the FAQ on the Acronis web and it sez that an uninstall in not necessary, however, we know that is not the case with 9.0.2323. I've been a TI8 user since early 2005 and never needed to read the FAQ Vive la 8.0.937 which is rock solid for me on several machines to USB drives both local and networked. It is probably plain dumb luck that the hardware combinations and other installed software I have is compatible with TI8 and that I have never had a problem except occassionally I had to do a second reboot on a Rescue CD to get the Linux version running okay when doing a restore/clone etc. Good luck all... I'll await your reports on the next build before resuming my testing of 9.0* My upgraded licence and $29.99US begs to be used.
