When i load the pmdg a/c and start a flight it freezes the sim and the keyboard doesnt work at all. This is very strange to me because ive had the pmdg 737s for a while now and havent had any problems until now. However i did recently install ultimate traffic last week because I was flying offline while internet was unplugged for a day. But that shouldnt affect the pmdg 737s. Whats the problem.

Hi Darien,Might want to check out the top post about CTD resolutions - this sounds like the issue with the missing sound file that was in the original SU1.1 update...

never mind i reinstalled and everything is ok now
