Printing from Acrobat 9.0 - Calibri font error

After installing an Acrobat 9.0 update within the last year, every time I print my company letterhead, I get the following error:

%%[ ProductName: Distiller ]%%

Calibri not found, using Courier.

%%[ Error: invalidfont; OffendingCommand: xshow ]%%

Stack:

[67 67 31 72 70 45 45 66 47 106 66 47 66 30 73 71 64 0]

([1] 

%%[ Flushing: rest of job (to end-of-file) will be ignored ]%%

%%[ Warning: PostScript error. No PDF file produced. ] %%

I assume that this error is due to the Calibri font. Is there a way to 'install' this font in Acrobat 9.0?  Or another fix for this problem.  What I have been doing is changing to another font, which yields its own problems (#'s printing around the logo due to tables in Word etc.)
