jup, me too. also I am getting this REALLY ANNOYING message about unsupported language again since I upgraded to 5. Once again all german, OS, base language of AS5, Everything. I check the Template, set to german, I check the INC file, set to german..I run the repackager wizard and create the ISM using the german template on a german installed OS with a german base of AS5 and voila..when I open it in my developer with also a base install of German default language..invalid language..honestly, what is the point in paying out 600 euro for a western language pack if I still have to hack all the files to get it to work????
