I am also having the same problem...

I had not had any crashes using the English until i began fighting the Timurids and when their elephants began firing the game would crash...

i downloaded the patch it it worked for a day, but now it crashes whenever I play them occasionally, but not as much...

I don't understand.

Also the part about:

Due to a timestamp check, the following unpacked files will
cause the game to crash and must be deleted before the game is
launched:

datadescr_geography_new.txt
datadescr_geography_new.db

????

The unpacked files don't contain any sort of files like these...

Anyone else having crash problems facing the Timurids? My problem is that if I let the auto resolve do my battles, i always lose against those dumb elephants and handgunners...but when I play myself I win...so the campaign will take fifty times as long. it is ridiculous.
