Maps won't load and won't even save properly

My older maps 2-3 years old no longer load and are suck on upgrading screen. My newer maps 1 year or less, open but fail to save. It says x number of changes saved, but it continues to prompt me to save as if it didn't work. I have to force exist the site each time in both circumstances.

Been a paying user for like 4 or 5 years.
