Error opening form - please, help

Hello, I am trying to open a form I need to fill out in Adobe Acrobat 9.0 and I get the following error: "error encountered while processing node xfa[0].form[0].CopyContent[0].#subform[0].GBU[0].nB[20].OV[0]. Unable to find suitable font for Korean encoding,

Someone suggested I installed the Korean keyboard, but didn't help either

The form is in English/French/Spanish.

Thank you in advance for any help!
