WEBENCH-POWER-DESIGNER: Webench Coil Designer: Unable to export CAD

Hello experts,

I would ask you for help to find what can be wrong that I cannot Export a coil to any of cad formats. 

After I select desired cad format and click Export button, the message "Processing CAD Export" appears, and after a minute it writes a message:

"CAD export was not completed successfully.

Please check your connection or retry your inputs to proceed."

I tried to export different coil designs, different computers and different browsers, so it seems should be something wrong on server side
