Answer 1

Thank you guys for the suggestions. I tried all of those and neither of them worked. What I ended up having to do was create a new User Account on my machine, delete the original folder to where I had my mappings and Redo the Get Process for my project and everything worked fine. I guess something must have been corrupt on my User Account.
