Microsoft.NET Framework Error

I recently shut my computer down to replace an old monitor with a new one. While doing so, I unplugged various components such as an HP Photosmart c6180 all in one printer, scanner, fax, copier, a laser jet printer, individual speakers (my new monitor has speakers included within the monitor). My computer (Dell) is set up with Microsoft XP Professional and is wireless running on a Time Warner Cable Broadband system. My HP Photosmart C6180 all in one is also set up wireless. After connecting everything back up and turning on the computer, monitor and both printers, an error showed up on my screen and I can't get rid of it! It is a Microsoft.NET Framework error that reads: "An unhandled exception has occurred in a component in your application. Click continue and application will ignore this error and attempt to continue. Object reference not set to an instance of an object" (When I click on Continue, nothing happens.) In the details box, it references the Exception Text as "System.NullReferenceException: at HP>CUE>Video.PlaybackControl..." and it lists several codes and Assembly Versions, but scrolling down to the end, there is a paragraph that reads: "JIT Debugging - To enable just in time (JIT) debuggging, the config file for this application or machine (machine.config) must have the jitDebugging value set in the system.windows.forms section. The application must also be compiled with debugging enabled.":confused:
Has anyone had this error before? What do I do to fix or get rid of it?

Initially I would reinstall the printer(s) but uninstall the software for HP first from add/remove programs. If that doesn't help, then use system restore to roll back a few days. If that doesn't work someone wrote down a fix here but if your HP printer is in warranty, I would phone HP before attempting it.
