Please offer some advice.

I got a licensed version from BUKA. Nothing has changed compared to the pirated version... I tried to install Equilibris. At first, it wouldn't install at all, then I downloaded 2 EXE files from the Equilibris website, replaced the originals with them - Equilibris installed, but as soon as I enter the game and try to start a campaign/scenario, the game crashes immediately, and a window with the error "memory cannot be read" pops up :confused:
How can I make it work with Equilibris?
The original version is very raw((( No battle grid, no possibility to play online, there are glitches. Equilibris fixes all of this...
