My projects won't open correctly!

Having trouble with LMMS? Ask about it here.
I recently had to reformat my computer, and I went to open one of my projects, but they're not working correctly for some reason. The sound is all distorted, and when I went to the folder I saved them in (on another hard drive) the icons were just blank and won't open normally when I click them. It keeps telling me that Windows can't find the correct program and I needed to select it manually to get LMMS to read it. So really now the only problem I'm having is the wonky sound. Are my projects screwed or is there a way to fix it?
could this be the 'charachter' glitch?
Does any of the path or folders on your instalation contain charachters not in the english codepage?
That will screw things up, and lmms wont load neither presets nor projects as expected.
The wonky sound.. Did you chose the SDL interface?

b.r.
I checked the directory and that was the problem, just changed it then went to SDL and everything is working fine now. Thanks alot!
