Sounds close - at this point I would try something trivial like
8 NAND gates in a test file ( uses every pin ), and confirm you
get what looks like a valid JED file.

CUPL was suggested, should you hit a brick wall with ABEL, right now it 
sounds more like a speed-bump..... :)

Finally got the time to set up a box with DOS. Didn't help much though.
I guess you were right about the need for a licence key. It seems like 
it worked for smaller designs, perhaps for evaluation purposes.
