I recently upgraded to MEP 2011. I cannot get express tools to work. I have them pathed to the express folder, and loaded the acetmain.cuix with MENULOAD. I have typed "EXPRESSTOOLS" and "EXPRESSMENU". Both state they have loaded successfully. However, when I try to use any express tools command i get the message "Unknown Command"
I had to Add/Remove Programs to install it from the disk. Then, I simply went into CUI and added Express to my current workspace menu. I did not have to path any folders or specifically load anything with MENULOAD. It works OK for me. Do you have the folder called Express in your AMEP 2011 folder?
