Hi,
It's probably best we exhaust Wouter's notion first before
trying anything else. The practice of symlinking (symbolic
link) is accomplished by using the ln command. There are
many different ways to shorthand the syntax of the ln command,
but the terse commandline would be;
ln -s "~/Library/Application Support/CrossOver Games/Bottles/bottle_name/drive_c/windows/system32/l3codeca.acm" "~/Library/Application Support/CrossOver Games/Bottles/bottle_name/drive_c/windows/system32/winemp3.acm"
You can open a terminal to do this, replacing the term bottle_name with the
actual name of the Crossover bottle itself.
Lets us know how that goes/if it works...if it doesn't help any,
I'll compile the wine library module for you to try...
Cheers!
