Hi - sorry to bring all this back up, but I'm having the same problem as HarryI-919 et al with the MDATA.00*, with a slight twist - if i ok the two errors I get (000 and 001) then the game starts, works as per usual, with the unfortunate side effect of having no cutscenes and no music. It's not a huge problem (I can still play the game) but it would be nice to get working fully... I'm using VISTA 64 bit and own the UK CD copy (i.e. called Supremacy, but haven't altered any filenames in my install) - and have followed the above instructions, I've even copied the MDATA folder into the rebellion root directory - no joy. If i follow budious' advice and try the "C:\Windows\sysWOW64\regsvr32.exe C:\Windows\sysWOW64\smackw32.dll after copying smackw32.dll to the C:\Windows\sysWOW64\ directory" (Which I'm assuming i use windows 'run' prompt to activate, then I get the following message The module "C:\Windows\sysWOW64\smackw32.dll" was loaded but the entry point DllRegisterServer was not found Make sure that "C:\Windows\sysWOW64\smackw32.dll" is a valid DLL or OCX file and try again. Am I doing something stupid? Also - if these cutscene files need re encoding, would someone be able to point me to a tutorial that shows me how to do this please? Thanks for any help that can be offered - I'm glad there are people keeping this excellent game alive!
