I've just gotten around to trying the AC-130 (Expansion Pack 2) that came with my C-130 X-perience All-One-Pack.   I've had no problems with any of the other C-130 aircraft that came in the base and Pack 1.

I get the following message when I select the AC-130:

"Visual Model could not be displayed  CSAC130EXTRA2 0"

when I look in model.cfg for CS_EX2_AC130 I find:

[models]
normal=..\..\CS_EX2_C130\model\c130-15
interior=..\..\CS_EX2_C130\model\c130-15_interior

BUT I find no .MDL file in the CS_EX2_C130 folder.  I search for a c130-15.MDL file in my entire AIRPLANES directory and find no such .MDL.  Everything else I need for the AC-130 is present - just not the .MDL

Same thing for the c130-15.MDL which is the LC plane.

What have I done wrong?  

My downloaded installer was csp131_1300.exe - 10/26/2010

Never Mind - I had moved a lot of unused aircraft to a remote hanger that FSX did not know about.  When I moved them back to ...SimObjects\Airplanes I forgot to move the base Expansion Pack folder - CS_EX2_C130 which contains the .MDL  files

Blame the ground crew!!

LOL. Glad you got it sorted out. Happy flying!
