mplay problem, deleting user profile solves it

[wuwang20]

Deborah reported on May 20 2014 that the mplay on teacher station 211 doesn't work, Matt checked it by using his account and it works. Deborah's mplay works on other machines. So we suspect there is something corrupted the mplay on her profile.
