when i am in the design maps tab and click to update my map by uploading the newest SVG, first it does nothing. the second time i click, it gives me an error message saying

Oops! For some reason, Flash thinks you're trying to open up two file browsing sessions at once. Please try again, and if this problem persists, please refresh your browser before trying again.

i tried refreshing many times and it doesnt work, help?

Maybe send a report message? I've had a problem with the map editor before and it actually got fixed.

Just remember to input the code it gives you.
