I use Andyfierman 's methond,hope others see can solve it too.Your files should all be at their last saved state on the EasyEDA servers. You will be able to reopen them (or restore to that saved version) when the problem is fixed. If you are still logged in, you can save your work at its current state by doing: document > EasyEDA Source... and copying and pasting the text in the window that opens as a text file in your favourite text editor. (There are instructions on how to do this at the top of the window.) You can then paste it back in and click Apply when normal operation resumes.
