I actually think I know what this is, as I've seen this same issue at work. I believe you need certain drivers on Windows.

This is official drivers provided from Microsoft. I believe what you need is to install the x64 variety. Try downloading that and see if it works. You shouldn't need to do anything aside from download it. Doing a little bit or research it appears RMXP is a 32 bit program, so you'll probably want the x86 version. Not entirely sure, but if the Rejuvenation EXE file is based on 32-Bit Architecture you'll need the x86, if it's 64-BIT you need x64.
This may not be the solution but it seems uncannily similar to what I saw about a week ago at work.
