Glad you're online, tell me one more thing, then can I say, whether there is a need to re-install, or you can do something else.
Namely, every time if you try to open something that you can not open, you get an answer that you are not an administrator and therefore can not be opened or you get some kind an error message. If You get error message something like 0x8000665, then is needed to reinstal, if You get answer, that you have not in administrator privileges, we can try to repair/improve/change this.
Awaiting.
