"your right beacause u shoulda use your backup and put it back instead of downgrading to 1.5 and upgrading."
That's exactly what I did. I had copied and pasted my old files back in, telling it to replace those with the same name. Then I made sure there were the same number of files to make sure nothing extra was hanging around. Then everything seemed ok, until I tried to enter an internet address with the keyboard. Thats when I suspected an error.
Then, I tried to downgrade, but the downgrader never even started. That's what I'm trying to get operational.
