Windows 7: My Documents folder messed up, it's a hidden shortcut

So I was working with moving my My Documents folder from syncing with Dropbox to Box and I messed up a bit. Well, at least I've found it and have access to it. Now I'm working on restoring a previous version.
Problem A: It's hidden and I can't figure out how to undo that because:
Problem B: It's a shortcut and I don't know how to switch that back to something that works
Problem C: It won't let me access the previous versions. It says:
"Windows cannot access \\localhost\C$\GMT-2012.09.07-20.26.55\Users\nicole\My Documents.
You do not have permission to access "" Contact your network administrator to request access"
I am the administrator and I have full access to the folder except for the "special permissions" check box which is grayed out empty.
Thanks for your time and help!

Try a quick system restore.

will that delete everything on my system between then and now?

It might, put what you need on a flash drive.
