Problems with units

Have NTW Imp Ed on Windows XP. Ever Since latest patch have not been able to recruit some units, like KGL in Britain, though Wellington still has his original unit. Had unit pack AUM and it worked fine before patch but since does not work. Have spent hours uninstalling and reinstalling including total uninstall without success. Any advice would be much appreciated. Note have tried to add other unit packs without success.

Note am not very pc literate so pse be understanding. Hope have posted on write forum

Has AUM been updated to the new patch? Have you asked the AUM team?

I do not think it is a bug and all other unit mods have been updated since the new NTW patch. Have searched your recommended screen without success.

If they are vanilla units, report them to the link I posted.
If they are modded units, ask the respective mod teams.
