Removing and reinstalling TB

Hello,

I need some guidance and hope someone is able to help me. I installed TB U3 flash drive and up until a few minutes ago, was using it without a problem.

I recently installed and ran a clean up registry program and do not know if this caused a problem with TB, but now when I attempt to open TB, I get a message saying that it cannot be restarted and must be re-installed. It then says that the program cannot be found.

If I uninstall TB and then re-install it, will I lose the email messages which are downloaded to the U3? I have some very important emails and do not wish to lose them.

Thanks in advance for your assistance. -AS
