Railworks America

My utilites application keeps giving me a NETFRAME box everytime. I had rwdecal and rwtool but I deleted them and had to restart my computer back to factory form because of my internet kept getting slow. (works now) but when I wanted to upload a JBHunt pack in railworks file. But I got the box everytime even when I uninstalled and reinstalled the game. Any help would be nice.

I think you need to install .Net 3.5.
