Nothing but crashing premier pro

I have been using PP for the last year and have established a Youtube channel.   But i haven't been able to post this weeks video cause I can't get it to export my video without the software crashing.  So today I decided to start a new video(though maybe just the videeo was currupt) and I havent  been able to spend more thatn five minutes at a time working on the new video cause pp just crashes the software with no warning and no error.  Am I the only person with this software that cant get any work done???
