Ugh. save failed with "Please enter the access key"

i was in my project, this morning, modifying a webform. Everything was awesome, until i tried to save it. now i am faced with the dreaded

I assume that means that I am going to have to reset my site settings, and thus will lose my changes. Correct?

I also get this message from time to time

I hope you find it helpful

I got this message again today
