I don't know about Xfire but you wrote something about MSI AfterBurner.MSI Afterburner was known to have problems with Enb series/iCEnhancer but the latest version v2.3.0 should fix that.IF Afterburner still causes problems after updating,try the free version of fraps if you want to monitor FPS and Xfire to chat at the same time.However, fraps is able to record only for 30 seconds or something like that,in the free version.Hope this helps.
PS-If you have further problems, post the event log from Problem Reports and solutions in Windows.
