I am using the GoG version and when I Patch White March it seemed to be fine with only 2 errors for 2 files I modded anyway.

However when patching the base game with GoG version 2.5.0.11 I get a lot of errors

Then the game loads and my cursor is the ground walk cursor and then it crashes when I try to load a save game

I have a huge list of patch errors.

In the patch log it states it is trying to upgrade from version 2.4.0.9 but in order to not have a pink mess in White March I had to patch the Base game to version 2.4.1.10  These numbers correlate to GoG versions

2.4.0.9 was patch 2

and 2.4.1.10 patched it to 2.01

However the patch 2.5.0.11 which is supposed to be from 2.01 to 2.02 is looking for version 2 which is 2.4.0.9

 

I have no freakin idea what to do and this is is a nightmare to figure out.

 

What patch for GoG am I supposed to use?

Totally confused at this point.

I was having all sorts of problems with the manual GOG patches and I ended up uninstalling, keeping my save files in the process (copied them elsewhere as well, just to be safe), downloading GOG Galaxy and reinstalling it from there.  Took forever, but got it working.  

I already re-installed once.

My bandwidth is not that great and its limited.

I am just confused why we do not have installation instructions anywhere.
