I know this is bizarre but I just bought a new router/modem this weekend and now when I try to edit any design assets, it just times out and never loads. I know it is the router because if I connected to a different network, everything is fine. The new router is a Netgear. Any one have similar problems or suggestions? So far the Marketo Design Assets are the only thing I seem to have problems loading.
In case anyone else comes across this, I discovered the problem. The firewall on the router was blocking access. When it was turned off, access was restored. It only appeared to affect access to the design studio.
