When you open a site in the Adobe muse application, this error pops up and the application closes !!! Most likely it's because I installed the "back report timer" widget and after the time on the timer has jumped out such an error! How can I now open a site in the editing application to remove this timer?
You can send me your .muse file which I can have a look at and fix.
Please attach it through Dropbox or WeTransfer and send it to me in a private message.
