Hi, I'm new to this site but I've come here to get some help with a real issue that's bugging me. I've recently bought the pmdg 737 and I think its a great simulation, however every livery I install from the website I end up getting a very buggy aircraft with the main issue being every time I turn on the dc battery switch I get this horrible irritating clicking sound which lasts the whole time and I know its not suppose to be there because the original livery from pmdg doesn't have it. Also some of the lights don't work either or are very inconsistent on any of the liveries downloaded. Its a real problem because I haven't spent money on this product just to fly around in the pmdg colours and need it sorted. Any help would be appreciated. Thanks.
