The crashing to desk top of the streached c130 & L100 i have found the cause,it was caused by one of the vc texture.bmp being saved in a different format as the rest.
Trouble is its been that long since the forum was working i have forgotten which one in particular was the problem,so if you copy and paste the following files from your c130 basepack into the streached c130/l100 models:-
C130_C1_T
C130_C2_T
C130_C3_T
C130_C4_T
C130_C5_T
C130_C6_T
C130_C9_T
C130_C10_T
C130_C11_T
C130_C13_T
this stopped my extrapack  for fs9 crashing to  desktop.
I also noticed that if you had the refueller c130,the extra pack would take the refuelling hose panel symbol out,and you could not operate the refuel hoses,my cure was to reload the c130 refueller,then rename the panel files in the base pack/and any other c130 you have installed prior to the extra pack,and then reload the extra pack.
You then need to edit in note pad the original c130 packs,so they call up the renamed panels.
some faults i could not fix,they are:-
1) on the streached C130/L100,the cooling ducts are not on top of eng1,but are halfway into the upper left wing
2) on the L100-30 if you open the ramp door,you can see through the area where the rear L/R doors should be from inside to the outside
3) on the c130j-30/c130H-30/C-MK3 i cannot open the rear doors
4) do not configure them to work with the ace,as the ski jato smoke will replace the eng smoke,and captsim did not do the models required for the vc digital flightdeck,hence the black hole discribed in an earlier post,where the eng digital gauge should be,and you cannot get the external tanks to appear,as this needs extra models.
Captian sim did say they where not ace compliant.
I have also done a paintkit template for the streached drum,and tested it on our va repaint,if captsim could let me have the info as to where i can send it,you would just need this in conjunction with the original paintkits.
