If you're new and not the original cobra using a alt-nick boy did you choose a poor username. You're going to get some serious flak over that one

The original cobra isn't the most popular person on the board at the moment.

anyway.
The path that the error message is giving you isn't important. It's simply the path that was used on the computer beloning to whichever programmer compiled FS2_Open 3.6.5.
What's important is where your own paths. Have you installed 3.6.5 to your freespace2\ folder? It doesn't like being in a different folder to the .vp files.
Juding from the error it's giving you I'd say that it can't find sparky_hi_fs2.vp. Do you have that file in the same folder as FS2_Open? Are you trying to run in anything other than 640x480?
EDIT : Hmmmm. Looks like the Forum weirdness we're currently experiencing decided that my answer was better and jumped it ahead of Phreak's
