I am getting this message when I try to "merge audio and DXI tracks into a wave file"

"Access violation at address 008120DE in module "RealBand.exe". Read address of 076A0000 at 008120DE.

It only does it on one song. I have no problem merging into a wav file on any other songs I have worked on.

2009.5 with all the patches. Does it on two different computers. The song file is on an external drive.

Any ideas?
