Source filmmaker not correctly opening? Halp?

[Abzero]

Alrighty then,well i was working on some animated vines earlier yesterday cause im a sad person and i closed it for a while to play tf2 and when i tried to reopen sourcefilmmaker it opened the loading screen then closed.
Is this happening to anyone else or is it just me?
also is there a fix for it,should've asked that first.
Thanks,
