What I had happened: I upgraded to premium (the 5 dollar option) and noticed that loading tokens, maps etc was painfully sluggish (before this, there were no problems at all, very quick loading just minutes before i went premium.) So I looked up possible causes, etc, and found your 'solving technical issues' and 'optimizing performance' pages. I followed the steps there, and some other general tips (such as flushing my DNS, making sure Java was enabled) and now the editor won't work at all, instead all I get is this: Nothing I do seems to solve this (all other web-pages i've tried work just fine.) I use chrome, as far as I know it's the latest update. My computer runs windows 7, 64 bit with 4gb of ram. Javascript seems to be enabled. I have Microsoft Security Essentials. Have disabled all addons and extensions. The Firewall allows google chrome (anything else it should enable, i do not know about) Have tried in firefox, where the editor won't load at all (not even the broken version)
