no, Ive extracted the mod using the .exe into a temp folder, then archived it into a archive (.rar).
Copied the archive from my "Big World DB" folder to the BG2 - SOA one's, then when time as come, used .exe and get that error.
Ill try to use the .exe and tell you how it goes.
Nevermind, it worked by using directly the .exe into my BG2-SOA folder.
Sorry for the trouble, Ill see to keep that in mind in case of later trouble.
