yes, i tried this too but it doesn't seem to be resolved. But I found the solution. I'd like to share it with you in case it happens to anyone, it's a rare bug but you never know. ok, after several attempts I tried to do various tests, I first tried to make a backup in a separate hard disk of gameguru and then bring all the packs, weapons, entities, etc. there. Then I downloaded it to steam gameguru again, so it was clean without errors. I then went back to using the gameguru backup to try to use the EBE, thinking that if it was far from steam maybe it would fix. Immediately nothing was resolved as I suspected when it was time to replace a texture with one of my own, the textures overwritten one on top of the other. so i tried to go and use the new downloaded steam gameguru EBE and get the default textures of the new clean install, and miraculously the textures were all fine. So what did I do to fix the corrupt old EBE backup? from the old backup EBE I made sure that it was going to take the textures from the new installation, and now the EBE of the backup version has also been fixed. I still don't know what the cause of this bug was, perhaps a corruption of some EBE texture, or file, during an old update from years ago (the problem is I've always had it for three years but I managed to use the slots in which the textures did not overwrite). So thank you for being available, I hope this system can be useful to someone in case it happens to someone in the future.
