Hi dbw,

I have just got the C130 ProPack (which includes all the extras) and though I've put few hours on the C130, I've had no problems of major note other than overcoming the learning curve for its systems and where all the bits and pieces are.  If you're already familiar with the C130, then it may not be an issue.

I use WinXP64, which doesn't have some of the compatibility issues that other folks have had (in general, can't say in regards to these products) and it's fine.  Like Ulf says below, he's on vista64 with no problems so that's a good sign.

The C130 is really a brilliant model, and as best as I can tell, it is accurate to reality.

I have a friend who flies C130 in real life, I can't wait to set him down at my sim and have him run through it to see if he can spot any errors. :)
