It would not let me update - kept getting 'unexpected error'.
So replying to add the following information
Seems to be happening with the latest download DAT file
Engine version: 54001158
DAT version: 6121.0000
This file found to be Wildtanget\gamechannel. However this file has been suppressed now. Simply wait approximately 30 minutes and this false will no longer exist or trigger on your system. Depending on the network settings you have or the caching involved between your system and ours it may take slightly longer for this false alarm to be resolved.
