I installed 3.1 and played it. It works great except for a tiny little error message that pops up whenever I start the game. The error message is : "Tag: TECH_ROEMERSTRASSEN in Info class was incorrect. Current XML file is Misc/CIV4RouteInfos.xml." BTW, I am using Sevomod with "sanctioned" UU addons that I downloaded from this thread : http://forums.civfanatics.com/showthread.php?t=175920 Probably the conflict may be due to the mod being at 3.1 and the mod addons being at 3.0... Is there anyway to fix this?
