I run vista on a new laptop.

I played ddo and it worked fine for a while

then mysteriously it stopped working?! After reading the forums with no sucess in solving this problem I found the solution!

Try this first:

Open internet explorer then file> make sure 'work offline' is not checked!!!

I use the opera web browser mainly and accidently selected work offline in IE.

the lesson is twofold:

1) DDO can think your not connected to the net if it precieves you as working offline
and
2) internet explorer is stupid.

this worked for me, hope it helps someone!
