Is MGE currently the most up to date visual enhance package still? I installed the latest version two years ago, so I was wondering if it was time to upgrade to a newer version, or something newer. I'm not sure how to check my version number.

Nope. Use http://www.gamesas.com/topic/1586344-shelter-from-magnus-blaze-19-mge-xe/ instead.

I checked, in my Morrowind folder is MGEXE.exe so I assume I do have MGE XE. So that's it?

You can check your version by right clicking the "MGEXEgui.exe" file, selecting "Properties", then looking under the "Details" tab for "File version". Or alternatively clicking the "about" button from the config tab in MGEXE's interface.

You mean when I open Morrowind and before I hit load? Bottom left corner says MCP 2.0. Idk what that means though.

That means you have Morrowind Code Patch (and not the latest). The MGE XE version should be in the upper left. Should be something like 0.9.10.

Nope, nothing there.

He means when you go to Morrowind directory. Look for MGEXEgui.exe file.

MGE XE 0.9.9 is what it says. MGSO 3.0 MGE XE.

Is there an update to this? If so, could you provide a link?

MGEXE, MCP, MPP and others are all updated since MGSO was released. There are also some other issues you may want to fix. Take a look at the http://www.gamesas.com/topic/1541166-morrowind-overhaul-sounds-graphics-30-thread-7/?p=24414374.
