Some time ago i installed this program, to test it, and see how it behaved compared with tuneup utilities… now i prefer S.M. over T.U. a few days after instalation i used the assistant that came with the download .rar but a few days ago, when i opened the program i was all messed up, and i couldn’t use it. i uninstalled it and reinstalled again but the problem persisted. i want to install it again as if it have never been installed on my pc, to see if the problem solves, at least until i can buy the licence for it, any one of you knows how i can do that? i mean erase every trace Of this program as it never was there? thank you very much
