Grr, it's a pr-downloader issue which the lobby uses to download new version of games and maps. It is maintained by Abma, one of the engine developers. The evo bug tracker isn't really the place for it. If you want to post an actual issue report, the weblobby tracker would be the best place: https://github.com/springweblobby/swl-qt/issues
If you want to get help with resolving the issue for yourself, please make a post on the forums: http://steamcommunity.com/app/291150/discussions/0/
and we can probably get you sorted out in no time. Sorry for the trouble.
