It doesn't matter which server I'm on (Thelanis, Cannith) or what character I use (various classes and levels), the store always looks like this.



There's also a little animated icon that appears briefly on opening, then disappears.

I've looked for and tried some suggested solutions, such as reinstalling .Net Framework 2.0. I don't use a proxy, and the other in-game windows (such as Ctrl+H for the help window) work just fine.

Any ideas? Any hints on what software the store uses (Flash? Shockwave?) so I can try different versions?
