Way to use .flac files in Audiosurf

After playing for a while, I'm now under the impression that corkscrews are in fact placed completely randomly in the song. Unlike other people who seem to only encounter them at intense moments of songs, I may have actually encountered MORE of them in the least intense moments of songs (intro, outro), in addition to some others which seemed arbitrarily placed throughout tracks.

However, given that on any given track, the corkscrews will always be in the same place, there must be some sort of operation going on that determines their placement, but I'll be damned if I have a clue what it is.

Anyway, this was too long for a comment.

There are many suggestions on how to fix this problem over in this thread on the Audio Surf forums but what it seems to come down to is the following;

Check that your filepath only has characters from A-Z and\or numbers 0-9. This fixed the problem for me.

Ensure that your Steam installation location and/or library location only contain alphanumeric characters. It is also worth noting that AudioSurf does not use CEG, so you can move the AudioSurf folder out of your steamapps folder to another location on your hard drive and run it from there.
