Rampage, each of your topics are in wrong folder...
When you need technical help, create your topic in the "Technical help" category, not in "meeting and events". Or, at least if you don't know, in "general discussions".
It's the last one I move your topic... next time I'll delete.
To answer your request, the solution is in the read-me.txt files, in the languagepack zip.INSTALLATION:
Replace your language.dll and/or xpacklanguage.dll (titans expansion)
file(s) inside c:\program files\microsoft games\age of mythology
Then relaunch your game and it's OK.
PS : this problem was ever solved here... please read before posting : http://aom-gr.forumotion.com/technical-help-f7/french-to-english-t276.htm
If you still have problems, we'll try to solve them by teamviewer.
The best defence is attack!
