I had no problem going to the EU (Thurgadin) after being on the US (Skyfire). But when I tried going back to the US I keep getting an error message saying the downloaded file is incomplete or corrupted. It says an update may be in progress and to retry in 20 -30 minutes! The updated file list also says: *Warning: Retrying paks/Voiceover1.vpk
I would check your background processes, that sounds like the client may still be running in the background causing conflicts with trying to download files.
