What version of the game are you playing?
If you see this on login, please send your output_log.txt file from the crashtastic_data directory to support@crashtastic.com
If you see it during a lengthy gameplay session, this is most like a bug that I am aware of.

Can you look in the host-file (C:\windows\system32\drivers\etc\host), and remove any reference to  api.crashtastic.com , and try logging in again?


If that doesn't work can you send your ouput_log.txt file from the crashtastic_data directory to support@crashtastic.com?

Sorry, not sure what this means. Can you send the details of your problem to support@crashtastic.com?
Thank you for your purchase of Crashtastic! I'm glad that you are enjoying the game!
This should have been fixed in version 0.4.4b. Is that the version you are using?
Working on performance issues for 0.4.5. Should be a good deal faster on these levels. 
I'm going to be moving the login system to the updater, so this won't be an issue for much longer.
