Hi and welcome to the forums
You have to download the official patch - number 1.10e here: http://www.ageod-forum.com/downloads/WIA_Patch.zip
This is a compressed (zip) file. To use it you can simply open it (double click it will do under Windows 7), inside you will find a file named "Patch_WIA_1.10e.exe". This isa executable file. To patch the game you will have to double click thos "exe" file and start the process of patching, similar to what you did to install the game. Make sure the selected path for the patch is the same as the one you chose for your game (by default it should be) and follow the on-screen instructions).
Then start a new game and see if you still have crashes. If so, feel free to report here, we will try to help you.
(PS: Later you can also install the quickfix (http://www.ageod-forum.com/downloads/Patch_WIA_1.10e_QF2.zip
), by a similar process.)
