dear fei

somehow you seem to have acquired inconsistent versions of
PsychToolboxDate.m and PsychToolboxVersion.m. I'm enclosing the
current version of both. That will solve the problem you have above,
and hopefully will allow ScreenTest to run to completion.

we expect to release the new version of Psychtoolbox tonight.

best
