Font size too small in Bridge

For some reason, the font size became very, very small while in Bridge....as well as all my image photo titles.  I searched Community and tried......"edit, preferences, interface>ul font size then restart."  When I got up to interface, I was lost.  It was working OK til now.  I'm currently using Windows 10 and CS5 (version 6.7 ?? unsure).  Any suggestions would be appreciated.
