Hi, I need help, I run PAD, then if I want to open the Flow for editing, I get an error, if I click the close button or the X button to close, the error shows up again, and again.

I can't copy or edit my Flows.

I can't reinstall PAD because I'm afraid my Flows will be lost.

How can I solve this problem. Thank you.

My error is in atachments.

error text is -

Ошибка = System.NullReferenceException
