I installed everything from scratch with the 2.1 update
I have no problem with 2.1 with X3TC.exe and dvm.dll from 2.0...
also in main menu i see 2.1
But i do not see treasure hunter missions for now... generally works
Sorry for the confusion
I play on Win7 x64 and i can not have vIDE in this time... I must wait for update :/
