--- Comment #95 from Yajo yajodj@msn.com 2013-08-18 11:22:02 CDT --- I think this can help:
I created a VM with Win8 x64. Origin also gets stuck frequently when downloading The Sims 3. The only difference is that it gets stuck less often (but it always ends up doing so) and does not throw error messages (I have to be looking at the progress bar all the time :S).
