Down to the description:
Alright. I decide to try out the Media VP's mod and see how well my computer can handle it. So far, so good... got 3.6.10.exe selected, got my Media VP's selected, click apply, then run. I start up the campaign, skip the training missions, and get going on the first real mission.
First thing I notice are these strange lines going about my screen, but apart from that... it jumps every little bit. I expected it since my graphics card is Intel(R) 82915G/GV/910GL Express Chipset. So here are jumps and framerate issues, ya sure... expected from that thing. Then all of a sudden... it crashes. Again, I figure it has something to do with my chip (also, 504MB ram)
So I go No Mod, and try running Freespace a second time (launcher 5.5e, most recent VPs and .exe). This time round, I expect better framerate, no crashing. However, I still get these strange lines (see image)

And FSOpen still crashes and asks whether or not to send an error report. This is on classic modeling, no enhancements.
I ran debug, and the log is attached
Retail works like a charm, but why wouldn't FSOpen?
