So I have switched to windows 7 and I wanted to download and play openbve. I followed the instructions and downloaded the 7 and the R62. It says there are issues along the route, but I downloaded everything. I click ignore and I can't operate the train! I released the brake and I am pressing Z and it does nothing even know its on level 3. When I go to exterior view, all I see is white boxes! Can someone help me?? I just deleted all BVE files so I can re-install it.
