Re: Cant download Sims 3 University on origin.
@volkypr Are you seeing the issue where you click the Download button and nothing happens? If so, please try this workaround:

If your computer runs Windows, just clear Origin's cache (again) instead of running the Origin reset tool.

I haven't heard of the Origin technical preview causing any issues in Windows, at least not this time around, but you can try disabling it as well.
If this isn't your issue, please let me know whether you have a Download button for University Life at all, and if so, what happens when you click it.
