MsVOLT… never heard of it before. The first two letters are already suspect. I’ve edited font in a couple of different font design software (Fontographer, FontLab), the only problem that I’ve encountered has been conflicting font ID numbers.
Did you try if it works in other software than InDesign or did this program mess the font up for every program? Such as MsWORD, or Illustrator, etc.
I (somewhat preconceivedly) expect MsVOLT to be the issue, not InDesign.
