[An Error after updating to V. 7.2.6.22690]

We've just updated our PV SYST to V. 7.2.6.22690. After that, we tried to open the shading scene of the existing saved project and got an Error window (see it attached).

Also, you can see bug report below. How can we fix it???

[Shadings animation]

Can't save shadings animation.

Press the button "Save shadings animation", then choose the way, press "Save". Error "Syntax error in the file name, folder name, volume label" . The folder name after Users - "???????????" - is in Russian (I can't rename it) and PVsyst doesn't support Russian. Could you fix this please. Or how can I change the way of saving "shading_1.jpg" files.
