Designer not saving or exporting after update

[Sabrini]

I just updated and now I can't save or export anything. When trying to use the export persona it gives all options but when I click export slices nothing happens, when I try to export just one by clicking on the individual splice nothing happens. When going through the menu bar I cannot export, the pop up comes up and lets me adjust all the settings but when I click export nothing happens. Same with the save and save as command. 

PLEASE HELP ME :(

Hi Sabrini,

Please could you tell me which operating system you are using?

Thanks
