Geopak SS1 version 8.11.07.246 post installation problem

I recently upgraded my installation of Geopak from 8.11.07.229 to 8.11.07.246 (on MS version 8.11.07.180).  Since then, when I activate Geopak, I receive the following message:

"Unable to resolve gpkFontMgr_getFontDgnNumber from lib gpkDgn.2.0.dll for 'DTMIC'."

Geopak is loaded, but I can't start project manager or use any tools.

Any idea on what is wrong before I uninstall this version and re-install .229 (that version worked fine).  Or will installing MS SS2 help?

Thanks!
