Edit text with Acrobat 6.0

[SexyDevil82]

I have been using Acrobat 5.0 for a while and I just upgrade to 6.0. I need to be able to edit text, but everytime I try, it say "All or part of the selection has no available system font. You cannot add or delete text using the currently selected font.". All my font are embedded. The PDF was create by a design company using a Quark file. I need to be able to edit text and delete image (usually using Touchup Object which is not working either with 6.0).

Anyone have suggestion what I could do or am doing wrong?
Thanks.

Apperently you have to have that font on your system (due to Abobe font licence) before you can edit it regardless of having the font embeded or not
