Bolt45, I got this issue resolved, least on my puter.
1. delete italy_1 from htc/ah2/terrains
2. download the AHitaly_1.exe file from the HTC terrains download page
3. run the exe file
p.s. I did a HD defrag, before installing the terrain with the run command
after I did all that, the Ct just let me in. Hope this helps you and others to get in.
