Loading game issue

xZROx

When I start up Crossfire everything works fine but im having an issue that when I click join game the loading game screen will pop up but it will stay at around 25% loaded and it will stop. I didn't have this issue before but now all of a sudden it started happening so I uninstalled crossfire and installed it again hopefully it makes that problem go away. I wanted to see if this has happen to anyone else?
