Hello,
I'm hopeing that someone has come across this problem before and can point me in the right direction.
I made the mistake of trying to upgrade from 4.03 to 4.35 which did not work. I then upgraded the announcements module to the latest version. Now when I try to drop the announcements module into a portal  I get this error:

A critical error has occurred.
Arithmetic operation resulted in an overflow

And all the content from the other modules dissappears. When I delete the module, all of the content from the other modules comes back?

I have tried using the module definitions link from host to delete and then reupload the announcements module from both the DNN 4.3.5 source package and the 4.03 version. No luck, same error. Anyone come across this type of error before?

Thanks,
Dan
