There's a multitude of reasons why this would not work. Client to server requirement is one of them.

Equip it?

Goodbye! See you soon!

Most launchers remember your login, whether you have a second layer of authentication or security. I have no issues with the current system only if wasn't followed by my second point. So is the case, but for me, very mandatory, in the case of an MMORPG. I agree. It's just that it also comes with old functions. A new, up to date design would allow for more options/customization. Such as custom bandwidth/speed restrictions. This of course could probably be implemented in the current design, but since this game is so successful, a new launcher design couldn't hurt. Not to mention the potential addition to a launcher friend's list, such that of Battle.Net.

The launcher is very outdated. Sure, it works. But it's flawed. - Requires login each launch. - Completely closes when game is launched. - Design/UI is very old. Here's hoping to an update that at least fixes the two first points.

I have no issues playing. Either the install is broken or something malicious is preventing it. I suggest you do a malware scan.

Each time I start the launcher I am forced to accept the terms after logging in. Is there a way to fix this?
