To people who say they have had problems with the patch please ensure when uninstalling that you remove all files in the ICC 2005 directory before reinstalling. There must only be the original files from an install for the patch to work. No custom backdrops, etc.
There are only 2 official releases of ICC 2005 I am aware of. The CD version released in the UK by Xplosiv and the SoftWrap downloadable version. Both of these have been tested with the patch and work fine from original installs.
If you are still having problems and have definitely followed the instructions above post exactly which version of the game you have and where you got it from especially if it is not one of the 2 releases mentioned above.
I say the following as an obvious thing but I am not implying people are trying to do it. The patch won't work with any warez version or any version where a SoftWrap keygen has been used.
Daniel.
