Well, thanks for the swift answer! Unfortunately, I did everything you told me, but I still receive the same "server failed to respond" error message.
Launcher (info):
[attachment=3041:launcher.jpg]
Client:
[attachment=3042:client.jpg]
Launcher (file):
[attachment=3043:launchnet7.jpg]
So, I checked all the boxes in net-7 launcher client, and have made sure that both the E&B client and the launcher .exe have administrator rights. The client is in the right folder, and as a matter of fact I had no installation problems whatsoever. Any (additional) hints please?
EDIT: I have a spanish version of windows, hope it won't be too troublesome for you guys ;)
