I have the DSL 2.1 download version, I got a link from craaig and it worked fine. The errors I'm getting started occur after I copied the files and made a second version of the game in which I installed the DSL 3 and Robot Wars 2013 mod. I'm able to make it through a few events and then when I reach the compressor arena the AI don't move, and then it crashes a error message appears and then is gone a few seconds later. This is happening in the DSL 2.1 game that I have NOT modified beyond downloading it. The modified one is the second one Containing DSL 3 and Robot Wars 2013.
Recap: Download, DSL 2.1, compressor arena game crash, have other RA2 game with DSL 3 and Robot Wars 2013 mod installed. Crash occuring with DSL 2.1 version.
