Empty Cmap on CmapCloud - URGENT

[LorieP]

When I opened CmapCloud this morning my Cmap was there in the right folder and the file’s title was ok too, but the Cmap was just gone, it’s now a blank space as if I did or completly erased it. The Cmap has been in this folder for months and I never had problems with saving it. I have an exam on thursday morning (May 13th) and I absolutly need this Cmap, can please someone help me? Is there a way to find a list of my Cmap past versions?
