Songlist isn't displayed

Hello evrybody, i just installed ireal pro on my Mac (Montain Lion 10.8.5). Songs can be imported but some tags and the songlist letters are all boxed "A" (see Attachment). Seems a Font is missing or not in the right place. Anybody seen this befor? Solutions?

Thanks for your help
