DRI texture problem

Hey, I installed the latest Update into new folder!
Step 1. First time when I loaded in the dry rock island

Step 2. exit run the cleanup.bat then run the game

Now the trees is good but still have terrain texture problem...
what's the solution?

 

Run the updater, your textures are corrupt. Delete the map's folder and the update will replace it.

 

Thanks, it is working...but strange bug!

 

Cleanup.bat!
