I changed nothing, yet TS isn't working anymore... Help?

[Iriabor]

For a long time, Teamspeak worked fine on my computer. One day last week, it suddenly stopped working. It could not connect to my server. It could not connect to ANY server. Since I'm not quite sure what changed, I'm not quite sure why it's not working.

Any troubleshooting advice?

A friend suggested it might be because I'm using it over a router, would that be it?

Try reinstalling (and delete the old folder before you do).

Make sure you also install the BETA version of the client as well.

Having a router *shouldn't* be an issue, as (by default) they allow all traffic OUTBOUND and only block INBOUND traffic.

The only thing that I can think of would be if you'd recently installed (or updated) a new anti-virus/Internet Security product - it's conceivable that product would have added/updated a firewall that's blocking TeamSpeak from making an outbound connection.
