Peter and Michael, Thanks for the reply. I tried the Highmemfix=1 in fsx.cfg but the problem persist. I tried to install the pmdg 747 that i bought with MD-11 to check if the same problem happens. The external model works but the VC doesn´t appear correctly. The puzzle for me is that i have 737s for the last 6 months and it continues to work without any problem. I had to uninstall the MD-11 and the 747s because it was shutting down my FSX when I load the airplanes in FSX free flight menu. So I don´t have the pictures anymore (the original ones I deleted after the first post, but it wasn't load here as you report). Anyway, if anyone knows how to fix it I appreciate! Tks!
