help! Opo Chano doesn't get my 2500 credits

[Geeno]

(sorry for my bad translation.. in the title is obviously wrong 'get' )

about the Czerka mainframe quest:
The first time I spoke to Opo Chano he asked 2500 credits and I answered something like 'I'll return with the money'.
afetr that I spoke to everyone else involved, I get the money from the Ithorians, and returned to Opo.
but it doesn't gave me again the speech option to pay!
only two options: the inventory and to leave.

I've returned to speak to the others npc involved but nothing's changes.....


I also downloaded the savegame editor here but I don't know how it can be useful in this situation

there is a solution? a cheat-solution? everything, 'cause Im' stuck in Talos 'til I finish this quest

THANX

Which mod is this from? Probably a poisoned buggy one :|
I can guess which one...
