I'm trying to load the Precursor's Remixes, but when I run the command from the directory with the actual executable, like so (complete with the error):
$ ./The\ Ur-Quan\ Masters --addon uqmremixes
The Ur-Quan Masters v0.5.0 (compiled Feb 11 2006 08:58:04)
This software comes with ABSOLUTELY NO WARRANTY;
for details see the included 'COPYING' file.

Initializing base SDL functionality.
Using SDL version 1.2.8 (compiled with 1.2.
Fatal error: Could not find content.


I put the remixes in the subdirectory addons/uqmremixes/ as per the instructions and the FAQ, but either I'm doing something wrong or there's something I'm missing.  Any pointers?

Thanks.
