[COMException (0x80004005): Cannot complete this action.

Question

Hi everyone, I dont know what is causing this, it just happened all of a sudden while I was working on the site, I am using sharepoint 2010, does anyone know how to fix it, cause everytime I try to access one of my workflow task it bombs and write this: " Cannot complete this action.

Please try again.0x80004005 Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

And a bunch of other things that are way too long to write here. Please help.

Thank you in advance.
