Just downloaded it 30 minutes ago and getting that Shader Error on start. :(
FATAL ERROR in Vertex Shader compilation
ShaderName: shdSwap
D3DXCompile failed - result
at gml_Object_MetaCont_Draw_76
I'm getting the same Vortex Shader error on the Steam version, are you able to update that version as well?
