Any help would be appreciated.

Resolved.
FYI this was caused by not upgrading my version of the Blowery Compression Module to the 2.0 version.

Curisouly this didn't really affect anything with my 4.0.3 installation on WinServer '00 running .net2.0.
It wasn't until my host moved me to a win 2003 box that issues arose.

Everything else with my 4.0.3 > 4.3.3 went smooth like butter...

Keep rockin' DNNers!
