Eurostile font clash


Apologies if a question like this has been asked and answered before, but since upgrading to Tiger my Adobe Type Library Eurostile will not activate in Suitcase because it is clashing with a font in the system. I have deactivated the system version of Eurostile in FontBook but it still doesn't work. It was working fine under Panther so it is something that Tiger has done to my system. Any ideas?
