* is a wildcard (test.txt = *t.txt), so that's what I did. But thanks for having a look. I changed it in the text above to make it more clear.

Edit:
Fixed! UAC needs to be off aswell. This probably has to do with the virtual store.

TCP works, UDP doesn't, I think it's not forwarded to the simulator. The default view (2, 200%) also doesn't work.
