My S4S doesn't show ANY mesh, help!

Hi everyone! I downloaded S4S last month and decided to teach myself creating cc. However, i realized my S4S isn't working properly. No matter i clicked on Build or CAS or Object, it shows nothing in the mesh library window... I'm using S4S Apple Blossom version. Also, because i don't have enough space on my computer, i installed both Origin and TS4 on my flash drive instead of applications folder. But the EA folder is still under document. Not sure if that's the issue

btw, here's the error message that always appears:
