Corrupted "Open With"

I understand about walking in circles. I am just trying to get clear in my mind what is exactly going on. I don't see the trouble of installing ultimate is worth it since you could probably reinstall Pro and have the same result. However, doing the scan I suggested might fix the problem. I don't understand why you can't tell me the name of the program you want to use or if your taskbar is locked or if you could provide a screenshot. (How's that for incorrect English? LOL)

Disregard my reference to a screenshot. I got it mixed up with another thread I'm involved in.
