The project or revision name contains one or more of the following illegal characters

Hello,

I'm hoping someone can help me with this. I'm getting the following error when I go to open a project from my second hard drive.

the project or revision name contains one or more of the following illegal characters and cannot be opened: ^&?*|<>:'

If I copy the project to my C drive, it opens just fine.

FYI, I have a 128GB solid state drive as my C drive, so I can't keep much on it. That is the reason I keep all the projects on my second drive.

Any help would be greatly appreciated.
