It's entirely up to you. Kaktussoft thought the repair option had not been adequately pursuued so I wanted to make sure you didn't feel you were pushed into the Clean Reinstall because I interacted with you about it, since you seemed to lean in that direction. If you don't have a perfect Clean Install to begin with, it is always preferable anyway.
System Restore is one of the many steps given in the tutorial you were first provided, so if you have a Restore point available it's worth a try. There are other steps there leading up to the Reinstall so that you know you've done everything. You would have read several methods to rescue your files if you'd made it that far.
