It's about time I got tired of waiting and installed the version 1 physics into version 1.1. All you have to do is copy three files from the Carrara 1.0 "Ext" folder to the Carrara 1.1 "Ext" folder. The files are WmDme.dll Physics.dta Physics.mcx (I think thats the right extension I'm working from memory on this one. The post that I found on the Carrara's Yahoo group had the wrong file extension so I just copied the two files that said Physics and the DLL)
