Registration Not Recognized

Hi, folks.

I have been using Visual C++ 2005 Express Edition for just over a month now and am happy with it, overall.

(I work on a Windows 2000 computer, usually logged in as a general user.)

However, a couple days ago I tried to start it up, but a message box appeared, stating that the 30 day trial period had elapsed, and I should register it if I wanted to continue using it. However, I HAD registered it right after I installed it.

Just to make sure, I logged out as a General User, logged in as the Administrator, and tried to register the product. I was told the product was already registered. I then logged back in as a General User. Again, I could not start up Visual C++ 2005 Express Edition. This time, I tried to enter the 14-digit registration key (I thought maybe it had to be entered for Administrator AND all users of Visual C++ 2005 Express Edition). A message box popped up, stating that the registration code was invalid. However, I had copied and pasted it directly from the e-mail from Microsoft. So now I don't know what else to try.

Any suggestions as to how I can get Visual C++ 2005 Express Edition to work when I log into my computer as a basic user Almost all of my work is done from the basic user account, and I don't want to have to log in and out of the Administrator account all the time whenever I want to program in Visual C++ 2005 Express Edition.

Your help is much appreciated.
