Hi Paul, it's one of the long awaited updates with a lot of the glitches sorted. If you want your history kept back up your MyLog file, download 5.00.65 and install to C://AirNav Systems to avoid the virtual store problems. Once installed fire up RB and once it's come to life and up and running, go to File - Database Explorer in aircraft you should find 80 odd thousand a/c rows, hit Database Update leave all ticked to update all records, routes etc. and after about 5 minutes you should have the updated file downloaded. Close down RB program and then restart, hopefully you'll have the full updated DB with some 210450 odd a/c rows now, and you're up and running, any problems come back and let us know - if I can do it successfully, anyone can! There's a lot of far more techy people in here to help you if you do hit problems.
