Huge Fonts problem

Hi all. I need help asap.

Few days ago I opened a file in corel x6 and bitstream font navigator found missing fonts and installed them. After that I found that a lot of my fonts are oartly missing and I mean for exaple Arial has only Italic and Bold Italic but no Regular or Normal, Bold and Italic... That happens with a lot of my fonts. Tell me what to do?

I'm with win7 64 bit and cdrX6 + font navigator 64.

 

Will be gratefull for help.

 

Regards
