ODK Aggregate

[Andrew Faust]

I am using ODK to collect info remotely from an Android phone.  Everything was working fine until a few days ago.  The App Engine has been error out and I have been unable to delete forms create for ODK Collect.  Any help would be great.  See error below:

Uncaught exception from servlet
