UPDATE:
Yes, it seems to work perfectly! You guys are great, you answered my questions before they even occurred to me. Thanks for being patient

@Emre,
I just saw your sample, and I think it might solve my new problem.

By placing the file into "FOLDER_LocalAppData" instead of "FOLDER_ProgramData" I'm thinking that would create a new file location for each user, and there would be no problems for users with different accounts.

Thanks again!
