SP1 and View Change

Ok so I've installed SP1. Gotta say that it's absolutely fabulous. I'm now flying smoothly even with light bloom and all sliders maxed out except for traffic.I do have one random problem after having installed SP1. After a flight is loaded and I'm sitting on the runway, I press the S key to switch to the external view. The view changes to external but the hourglass comes up and FSX starts loading something. After about 10-15 seconds I get an error regarding a fault with FSX.EXE and I'm given the option to restart FSX or not. I'm not 100% sure but I think this problem only occurs when I'm using ACtive Sky 6. I'm also using the latest version of FSUIPC(unregistered). Does anyone have any insight on this? Thank you.
