Unable to open file. File contains corrupted Physical Workspace data..

[flowing]

I cannot open a file that I have worked on for several sleepless days and nights and spent so many hours....

How do I fix this? Maybe there is a way to disable that Physical Workspace? A way to edit that data? ANYTHING AT ALL TO MAKE IT LAUNCH?? I'm desperate....

Hi, I had this problem, but to solve it I changed the language on my NETACAD training panel to English and downloaded the file again.
Earlier I tried with another version of PacketTracer without success.
I'm taking the course in Portuguese and that caused the problem.
The screen that I will attach is from the file downloaded from the page in PT-BR with 1,123KB  and from the page in English with 1,128KB.
