Error while openning file.

[Robert Merkel]

Hello,

first many thanks for the cool program Lunacy.
Unfortunately, I got a problem after 5 days of work.
When opening the .sketch file, a pop-up window appears where you can: Can't open file. wrong format or internal error.
.....

I hope you can help me because I've already put a lot of work into it.

Thanks in advance.
Robert :)
