Check for "Null" straight after loading, and check the others too, if they are fine, try replacing the LOGO image with another random one, even copying one of the paths above, maybe the original is corrupt. If it loads fine and null isnt returned after loading, obviously something is going tits up on the way... So check for null again before that line that throws a wobbler... Then, erm, check if it has been free'd or whatever before then and when, maybe try a FileExists on the path as well... Basically, chuck the kitchen sink at it.
Like Tom said, copy and paste the project out of "Program Files (x86)" and dump it somewhere writable so windows doesnt butt in.
