Hey Johan,

First of all, you're writing in the wrong forum section. This one is dedicated to the FSX version of the C-130. For the FS9 version,
go here: http://www.captainsim.org/yabb2/YaBB.pl?catselect=130.

About your problem: try the steps explained in KB 182 in the customer support.
Have you looked in previous posts in the FS9 forum section? Maybe someone before you had a similar problem...
I don't have FS9, so I can't help you further, but I hope you get it working!!
