I am not sure if there is a direct correlation, but this is what I think.
I use to be able to play on online game that is in development.
At some point in time in the last month I installed some new codec pack to view movies properly with audio and video.
Also at some point in time in the last month, I can no longer play this online game. I can log in and launch it and it loads, but right when it gets ready to show up, an error box.
Are the two connected, of course you can't know for sure. But has anyone else had similar problems?
