Thanks, that link definitely worked.

There are 2 possible files that can be downloaded. One downloads as MCongif.xxx and the other downloads as setup.xxx (executable files). You want the one call just setup. Right click it, run as administrator. Choose "advanced installation". This brings up a window that has 4 checkboxes, one of them is still unchecked called "legacy Configuration Software". Place a check in that box and run the install.

The first time you run the software it will look pretty much exactly how we always were used to with the old legacy program and it functions exactly the same as well (did for me).

Got out my old serial adapter and plugged it in and viola, instant connection to the 800. Now to troubleshoot my next issue! This issue is closed.

Thanks!
