i had this same problem
my batchrenderer did also not even finish one image
it had for me to do with my NOD32 antivirus
this batch converter seems to use some kind a network stuff
when i reinstalled a new nod32 smart security and putted this one on asking for permission when software uses the network i alowed the batchrenderer when nod asked me what to do with it
now it works fine for me
i found a program that i could run with my old nod32 version when the normal mayabatch did not work
i uploaded the file for interested people
but in this i did not know how to config it to get nice good quality images out of it
it works with code looks like MELcode which i do not understand, maybe one of you does, and is this for him/her the solution
once i contacted the maker of this thing for help but he did not answer.......
all the best for the new years .......
