Cant connect to nq server (2.60)- IP: 178.63.72.133:27960

A few weeks ago i didnt have any problem connecting to any of the three nq servers, till now. When im connecting to server, i get this error message: '(Local file existis with wrong checksum)'.

I deleted couple .pk3 files that i had in nq folder and that way to download them again; even while im downloading this file, i get the same error message.

I've reinstalled the new FA menu, to see if it solved the problem with that file, but this server is not even on the menu, even i have to type the ip manually to connect yet...and no, the problem remains.

Update: the problem is unresolved yet... i get same error message today.
