The second site was really slow from where I'm at (sweden), but it worked in both FF and IE.
Do you have a slow internet connection? Do other Flash sites work?
Check if this folder exist and has content:
C:\WINDOWS\system32\Macrom
ed\Flash
Go here for a guide on how to adjust the timeout in IE:
http://support.microsoft.com/kb/813827Here's how to do it in FF:
Type "about:config" in the FF-address-bar.
Filter on "timeout".
There you'll find values for "network.http.keep-alive.t
imeout",
2network.proxy.failover_ti
meout", and so on.
Doubleclick a value and set it higher.
