Importing audio

Hi,
Since upgrading to cubase 8 pro I am unable to import audio files from the menu. When I go to import I get the spinning wheel of death (Mac Yosemite) and a window appears then it takes about 5 minutes before any folders show up in that window. Previous to the new upgrade in 8 pro it all worked well. But since upgrading the new update I have been having this issue. Please if anyone has had the same issue or knows how it can be fixed, I would be really appreciative.

Cheers
