K, put everything back into the dominions 3 folder. Removed the new project line (left in the fiddle xp line). copied Aran.map to the semirandom folder.
Opened random, typed "aran" into the yellow box, hit semirandomize. Got the below (same as user above my earlier Fubar)
Adding stuff... /
---Error in main, line 1692: index 1 (=-1) out of range
---Error: Program stopped due to an error
---Program done, press RETURN---
Attached is the testdump, there is also a new text doc called neomatrix.txt.
I ran through your tips above and it worked though... thanks, sorry for being so thick.
Edit: Yup everything is working now. Playing a 2 player Aran @ 100% fiddle so I can have time to see the new GANs... some are very intimidating

Bout turn 20 and have seen 6 or 7 so far. One had like 300 units with hoburgs/ants and such... can't remember the name. Went down easier then i thought it would. Playing the Urdheim nation which I'm currently liking.
