Commands coming up unrecognised

Hi Everyone

I am having huge problems on my Acad this morning.

Commands such as Matchprop and CUI are coming up unrecognised and quite a few others.  Matchlay is also coming up unrecognised.  I have reinstalled AutoCAD and I have reloaded the acad.pgp file. I have tried the icon, the ribbon panel and the keyboard short cut to no avail.

I also couldn't edit attributes by double clicking on them but I could by typing in the shortcut.  It seems in AutoCAD classic I can doubleclick and edit the attribute but still so many of my commands are coming up unrecognised.

Please help its driving me mad.

Steph
