As far as I know, there is no "1.10" upgrade...well there might have been a long time ago before 1.2 came out but thats too far back to remember for me. You need to download the patches mentioned before in this thread.
Edit Oh there is a 1.10 update. Forget that update - you don't need it. As said before, get these...
Ultimate upgrade2
Ultimate Upgrade 3
Patch 1.46
...and install them in order.
