I have Acrobat 7 and don't have that option, but I do have one that says Convert True Type to Type 1. It was checked, so I unchecked it and tried again and it didn't work. I still have Corel 10 and everything works just fine. X4 says the font in question can't be embedded but version 10 doesn't say anything (which is why it probably works!).
I might be reaching WAY out there and am not sure if this would cause it, but read below and see if it could be a problem:
The creation date of our copy of the font is 1992. I don’t know if a more current copy exists, but the one that resides on our PC’s originated from a real early version of Corel. When Corel was originally installed on our PC’s, we had Windows 3.0 at that time, which was a 16 bit O.S. Windows XP, which we have now, is a 32 bit O.S. Not sure if that would have an effect or not, but you never know. Ever since Windows 3.0, we have upgraded operating systems from 3.0 to Win 95 to NT and then to XP. Corel software upgrades here have gone from 3 to 4 to 5 to 7 to 10 and now X4. Even with all of the computer upgrades, the original hard drive contents from “back in the day” are maintained because our IT department just images the hard drive and transfers that onto a new hard drive. Our IT department has Corel on a server now with seat licenses, so only the program files our on our PC’s and not the entire disc contents as if you were to install the program onto your PC at home.
Thanks for everyone's help,
