Making progress. With the help from GoG customer service I was able to download the file Kevin send to GoG last friday. It seems if you download through the website you get the correct file. Through Galaxy client you do not for some reason.

Did a clean install of DoS2 + Engine Editor. No more version discrepancies and you might think its time to get working. Another issue arose hehe...

"Syncing fixedstring (null), if possible register it in the networkfixedstrings. Only allow it when it's not used too often (levelswap, ...)" <-- it is the only error debug is providing. and I still can't assign a TR_ texture to start working on a map. Assume its due to this message.
