I googled "Rundll error" and got some links like this:
It means windows lacks a program to run an application, maybe the online. Not sure ift that's possible (Perhaps a trojan - best run anti-virus software).
If this doesn't help, then google some more. Most faults you could run in too with PC's, have a troubleshootingquide or tips somewhere on the net.
In the wilderness we go alone with our new knowledge and strength.
