Premiere Pro crashing constantly

My Premiere keeps crashing. I think it has something to do with the audio enhancer. It's not the PC's fault, as it's new, Premiere worked great on it until recently. Now I have to edit a wedding and can't do it. I managed to make it work yesterday by unisntalling and installing other version, but I think it got updated again and now every few seconds, it crashes. I am supposed to deliver the wedding today, wtf?
