Coldel, why don't you do it properly? I mean fresh install like this:
1. Download iBackup, save everything you need on an external drive: mail accounts, favourites, cookies, movies, pictures, music, documents, etc, etc
2. Write an USB drive with Mac OS X Lion 10.7
3. Boot from USB holding ALT/Option key, open Disk Utility, wipe everything and then install Lion brand new
4. install iBackup again, restore ONLY FILES NEEDED, no preferences, blah blah.
5. install Photoshop, Office for Mac, Firefox if you use it, etc etc
6. ready to go!
Any problems ask me here!
Good luck!
