where did you download it ?
if github = you need 2 git hub to make it work
download it from this link
http://browedit.borf.nl/browedit.zip
if you still have error
make sure that your config dose not miss ( , )
example
like this you will get error
"C:/Users/sader/RO/data.grf"
"C:/Users/sader/RO/rdata.grf"
this the right way
"C:/Users/sader/RO/data.grf",
"C:/Users/sader/RO/rdata.grf"
