This is normal in Windows - this system just can't connect to the same 
share/server with different credentials.
So if you're already connected to that share i.e. as Administrator, you 
won't connect to that share as a different user.
Workaround - use a different server name.

It worked before for you by pure accident, as this feature was never 
planned. Now it doesn't work, as one slight bug was fixed.

However, it makes perfect sense to add a switch like "use computer 
account credentials" for connecting. So it should be added to the next 
version.

I'll try to upload it this week. Or, if you want to help with the code, 
I might do it earlier, let me know.
