Hello. In RSRBR2015 mod, after update 01, I get this error: Physics file absent. I had the same problem with RSRBR2014 but as here, after I instaled updates. Nothing helps. I know this is propably an issue with 7zip and windows 8. Only solution I have found is to format/clean installation of windows but I do not want to do it. I tried with reinstall of RSRBR / RBR, both 32 and 64 bit ver of 7zip copied to RBR folder, I added all exe files to DEP list. Nothing helped. Does anyone have any sugestions?
