0 sizes free on host's mounted shares?

Hello.

I share my Mac Mini's updated Mac OS X 10.7.5 host's desktop and its subfolders into an updated Mac OS X 10.8.3's guest VM (Fusion v5.0.3). I can access and read my host's shared data just fine, but I cannot write to this host due to zero free space? VMware Fusion's sharing settings show read and write access for these shares. Why? Did I miss something? I have no problems with connected network shares though, just not non-network host's VM shares.

Thank you in advance. Image may be NSFW.
