Is it possible to downgrade from TI 11 to TI 10 Having used TI 8 for a couple of years, I figured It was about time to upgrade. Yesterday, seeing the special offer, I took the opportunity of downloading TI 11. Have to say I am far from impressed. After a few niggles in trying to install the S/W and create a Boot Disk, On testing I find that the Boot Disk Won't work: It gets as far as the "Pick a Task" window, but I'm unable to pick a task as my mouse freezes. I've tried F11 "quiet acpi=off noapic" with no success. I can't believe that Acronis still haven't fixed this problem, it was there in TI8, although "quiet acpi=off noapic" worked for that version. Without a usable Boot Disk TI 11 is pretty much useless for me. I've spent most of the afternoon trying to figure it out, and not too keen to spend more time on it. Having checked this forum the consensus seems to be that TI 11 is very flaky, while TI 10 seems to be more robust, So I'm hoping that a downgrade is possible.
