VPHOT Broken?

After several attempts at uploading data, and re-uploading data which seemed to work fine yesterday nothing is working today when I try to view the images and get data.
Uploading the FITS images (zipped or unzipped) seems to work ok, and a test upload says everything is fine.
But when I click on the link to view the image I get the following error message:

Server Error in '/app' Application.
Exception of type 'System.OutOfMemoryException' was thrown.

Is it broken, or is it just me?
Yesterday the images opened, today those same images gave the above error.

HELP!!
