Can't Import Multiple Files Into Vegas Pro 10.0e
 

I never got this issue before, but all of a sudden, I can't import multiple files into the Vegas project at once. When I select all the files in a folder and try to import them all at once, I get an error message that says, "You can only choose multiple items only if they are located in the same folder." The problem is, they ARE all in the same folder...I've never gotten this issue before for importing. It's always worked fine until now.

So...any help would be appreciated. Thanks!
