TW doesnt start

Hi.
Suddenly stopped running TW maps (bg01-bg06). Before they worked normally. I got two territories. After some time they broken. I tested to start them up on two different servers. On both of them I got the same error below.

I dont understand what the magic happens, and how they worked before. And why they dont want working now.

There no modifications made since maps worked normally.

Any ideas?
