I get the way to fix it, but i thought maybe you need to change your program. I cleaned the text in Maya.env file, it worked. I changed the plugin and script path by the .env file. If i use PiSquare, i can not the our tools in the server. So, please fix it! Thx!

I sent it to u, please have a check. I might know what do u mean, but there was no pisquare ui showed if i run the script below in my maya mel script editor.

Yes, I've tried with the english version, it didn't work...
