Boinc manager won't run after update

Just got a boinc update. The boinc manager won’t connect to localhost. This has happened in the past, but “fixes” are years old. Here is the error message:

**linux:/home/prexy #** boinc-manager
ln: failed to create symbolic link '/root/./gui_rpc_auth.cfg': File exists

(boinc-gui:22296): Gtk-WARNING **: Theme directory base/ of theme oxygen has no size fie
ld

execvp(/home/prexy/boinc, --redirectio, --launched_by_manager) failed with error 2!
execvp(/home/prexy/boinc, --redirectio, --launched_by_manager) failed with error 2!
execvp(/home/prexy/boinc, --redirectio, --launched_by_manager) failed with error 2!


Any ideas?
