Quote - Did you install in the same folder as the old version? perhaps the new EXE didn't get written? or maybe one of the DLLs ...

 

Maybe try a clean install of 1.0RC4? (after this one is done rendering No need to fix it if it's working to your satisfaction with .8)

Ugh.. so I reinstalled 1.0rc4. and now its pointing to version 1.0... should I start all over in the new version or continue the render in 1.0??? WHAAAAAAHHH!
