Hello, my EM4 started crashing at startup, crashing started after i installed some codecs, so i think that is the problen. I Saw this in logfile, it may be the problem, but i dont undestand it ?VulpineWrapper::ChangeScreenMode(): VERR_NOSCREENMODE - Screen mode could not be set un installed codecs i installed but it didnt work. Note from Stan. It didnt work for me, dunno whats the problem
