Ok i've sorted one problem...i had my mod in the install directory, and i was told there was a problem with it, so i moved it to my documents and it now loads.
I now have a completly different problem, i've added some elements to the CIV4TechnologiesSchema.xml file and added the new values into the CIV4TechInfos.xml file, it does load the CIV4TechInfos.xml file, but ignores my new additions and says it's expecting some thing else, so now it looks like it's ignoring my CIV4TechnologiesSchema.xml
Cheers for the help.
