Problem running batch convert job from command line

Hi I am running a bcnv from msbatch batchconvert on the command line, this is working fine on one PC but on another it fails.  The bcnv and csv files are on the network.  I have tried running the bcnv manually from within microstation on the PC and it works so I cannot understand why it fails at command line.  Could it be something to do with the path depth of the folder the bcnv looks in for files to convert?  Although again, the path depth is the same on the other PC that it works on.  Both PC's are running windows xp and have Microstation V8 2004 installed. 

On the failing PC the bcnv runs but doesn't come up with the files processed files completed etc in the dos window...any suggestions?
