I always check first for a new version of cmpro and I'm using the mame executable or .dat files from mamechannel.it (I think they are as official as it gets, if not from the official page). (Incidentally, I always compile my own version of SDLMAME when an update is released. Is there a way to create a .dat file using SDLMAME?)

But I'm still having the above mentioned problem. I have 3 folders for my ROM files: 'ROMs', 'CHDs' and 'LDs' (I think the names are self-explanatory). I make sure the paths are added to cmpro's preferences.

Taking calspeed as an example, I have a folder called 'calspeed' in the 'CHDs' folder, inside of which is 'calspeed.chd'. Same goes for calspeda: 'calspeda.chd' inside 'calspeda' inside 'CHDs'.

Both files are correctly identified and pass the SHA1 test.

I first thought maybe I mixed up calspeed and calspeda. So I exchanged their names and positions. But cmpro correctly identified the two files and reported them as calspeed and calspeda, respectively. If I rename calspeda to calspeed, cmpro reports "missing but fixable (-> calspeed) chd: calspeda.chd". If I reverse the name change, calspeda is reported again as unnecessary, if I delete calspeda, next time I run cmpro it is reported as missing. If I put 'calspeda.chd' inside 'calspeed', cmpro reports "wrong placed chd: ...CHDs\calspeed\calspeda.chd (move to set: calspeda)".

I'm completely lost here :-(

I hope my explanations were somewhat clear enough so some kind soul may tell me that I'm stupid and what I'm doing wrong here.
