iPad won't sync apps "computer is no longer authorized"

[heyitsmeneil]

I'm trying to have a factory reset and now syncing my apps but iTunes is preventing me to sync showing this message.

Help please.

P.S. I already authorized like what iTunes said.

You authorized the computer and rebooted it? Can't see why that wouldn't take care of it. Maybe nuke cookies and history just be sure and try again.

I had that happen after reinstalling Win7 awhile back. Apple techs told me to de-authorize all my computers first, then authorize. It worked after that.
