Administrator Privileges In Windows 7?

I've searched a number of other forums, looked under Admin privileges in the search panel, checked through the other threads as far as I could, and checked references to Naturally Speaking but cannot find a solution to this problem. I'm not at all technical so will need word of one syllable aI had a local company build me a new computer. I installed windows 7 on the blank disc with just one single user (me) who was classed as administrator. Until recently it worked fine. I installed Naturally Speaking on it and set up a profile. It worked fine from the initial session after installation but, after it had been closed, whenever I tried to restart it the program would load but any attempt to load my profile got the error message: The user file you have selected cannot be accessed. This could be because you do not have sufficient privileges to use it or because it is being accessed by another program."

Attempting to run the program as an administrator gets the message that it cannot be run in enhanced mode. I contacted Nuance (who make NS) and had a long correspondence with them.had no effect.After uninstalling and reinstalling a couple of times and ending up with the same result, I uninstalled it and ran a removal program from Nuance to clear every trace of it. Just recently - to solve a problem with windows that recently appeared - I reinstalled Windows 7 using the update facility on the Win7 installation disc. This worked fine and once again I only had the one single user who had administrator status. There were no working guest or other users.I tried Naturally speaking again with the same result. Once again I completely removed it from the system. I then set up a new user with Administrator privileges. Going into that user I installed NS again. This time it worked fine. I can start it from that user and it works well. If I go to the first user screen there is also an icon for Naturally Speaking but once again, if I start it I can't load my profile with the error message above.

It's not particularly convenient if I have to switch users to use NS. It all seems to be to do with Win 7 Administrator status. Can anyone suggest a way that the original Administrator (me) can get the same administrator privileges as the second user seems to have under his administrator status. It seems a ridiculous situation that one user can use it while the other can't.Sorry to have rambled on but I was trying to give as complete a picture as possible.[CODE]
