Then you have the bugged version, and may experience crashes in a few different ways..  Don't worry, you still get the nude texture with v4.1, just the default "free" texture with the crappy blue undies and swirly painted hair is added in besides.

So do you suggest me to update to 4.1?

Then there is a good chance you broke some of your content even if you don't realize it now, because many things within different content files refer to file/pathnames that you may have just renamed.

Well, I tried not to rename any of the add-on folders I've installed, at least not the ones which were requested to be kept untouched as specified into their ReadmeS.
If by chance I ever unintentionally broke some path,  do you know if there's a way different by the straight  uninstalling/reinstalling content to check out and eventually correct the broken paths?

Thanks a lot for your steady assistance Pjz99, it's something anyone should pay for  :)
