Can't say that I'm shocked by this, but jitspoe wanted me to make a post about it.
I've been trying to help out with the sounds and in order to get them jitspoe has said to install the new versions. When I tried this with build 24 it became the new association for DP, even though it was in a separate folder. For example, serverbrowser automatically went to the newest version of the game on my system. I would guess this is a windows issue, but have yet to install a different version onto another OS to find out.
Jitspoe implies that a new installation should be discrete of an older one. If someone knows how to do this, please reply.
