Unable to get editable tasks error

I'm getting an error while clicking on the Tasks section of mediabin desktop client. The error message is "unable to get editable tasks from the Task Catalog. An unhandled exception occured while 0x80040416)". The task list shows only the get original, insert unmodified and none tasks. Importing or adding new tasks also does not seem to work. All other functionalities looks good on the server. I'm logged in as admin.

The error is there on the webclient also. The task list while adding an item or retrieving an item is empty. I checked the IIS log and the asp is throwing the same error at line 582 in additem.asp. This is not a new installation and has been working fine till yesterday. Checked the database and I can see all the tasks listed in the TaskCatalog table.

MBP.log also does not have much details. 11/23/06 16:48:05 ERROR: ConnId:2 Request:CGetTasksRequest Reason:An unhandled exception occurred

I restarted the mediabin service but that also did not help.

Could it be that a DLL has got corrupted? If so, which one?

Any help is greatly appreciated!

ENV: MB 4.5.3/Win 2003

TIA

It sounds as if there may be bad data in the taskbodies table. This has been known to happen on rare occasions especially with tasks that have been upgraded from older versions of MediaBin (there were significant changes during the 3-4 transition and the 4.0-4.5 transition. There should be no issue changing among flavors of 4.5, and in most cases there should not be a problem even with those upgrades, however it is often useful to XML export the tasks and metadata definitions just in case prior to an upgrade.

Support should be able to help you backup your task data and then try deleting one task at a time from the tables until the problem does not appear. Of course, if the number of custom tasks is relatively small, it would be much faster to delete all the tasks and start over but I do not know from your description how much work reinitializing the custom tasks would entail.

Thanks Lyman. We have around 20 custom tasks and I had copied over the tasks from a 4.5.1 system to 4.5.3. I exported this as XML and it seemed to be imported and working fine. I'll probably delete all the custom tasks and try again.

This error was resolved by deleting all the custom tasks in the TaskBody and TaskCatalog tables. Probably there is an issue in importing tasks from 4.5.1 to 4.5.3. Thanks for the help!
