Troubles with DX2(admittedly form a "newbee"

I have DX2 installed and all was great in DX land until I switched(like I often do) to one of my favorite DX Themes- DragonismII--Then all H-E-double toothpicks--I keep getting an error that just goes on and on "doh" and then something involving the "dragon player" I have tried just about everything I can think of to fix this - but the errors keep shutting down DX2 before I get a chance to edit the scripts for the "dragon-player". Can someone please instruct me on how to fix the problem - or is this one of the bugs in the beta version?
