Sean,
Before you start installing any MOD into the game, you need to make sure that CoAS "Vanilla" works including setting the graphics settings and keyboard commands.
You need to do a "test run" first, to eliminate the possibility of system incompatibilities on your computer.
One thing that immediately comes to mind in TAGES DRM protection, that can cause immediate CTD. This can be fixed with updated drivers which you can find here on this site.
My recommendation is to download the NO CD fix after installing the new TAGES and this potential issue is removed which also can be downloaded here on Pirates Ahoy!
Bottom line - Once you start overwriting files, almost no one will be able to decipher what is the problem source as only you know what you overwrote and there is no error log to review.
This is particularly problematic with some parts of Combined MOD and GOF, as certain parts are not compatible with each other.
Hopefully you are not trying to combine both mods or the game will definitely crash.
Pick either GOF 1.2 or GOF 2.0, but not both.
DO NOT add in parts of Combined MOD on top of either mod as things as simple as ship files will also kill the game.
DO NOT add in additional external mods, unless you know what files are being replaced, what they do, and how they affect the game.
Graphic files generally cause no issues, but may others can cause havoc, even after starting a new game.
Also, before you attempt to install again, make sure you CCleaner or equivalent to get rid of any old installation, including any personal settings before you try again.
This game will run fine in Windows 7, 64-bit with no problems even using Intel Graphics.
Best Regards.
