I`m getting this error when I push ok. I`m using my ultima folder as path. I`m missing files texmaps.mul and texidx.mul.
I`m using Ultima Online Renesance and 2.0.3 client!
I would like to get help.

That's probably too old then. Is there any particular reason why you can't use a newer/recent client?

[Ever1x]

because of brother who plays with this client in one server and doesn't want to update!

You can still copy all required mul files from a more recent installation ... you don't even have to replace anything for that, just keep it separate from your UO installation.
