Error on starting Client

[Jamilian]

Hi,
a friend of mine can't login, because he gets a white screen and this error:

Any Ideas?
It seems like the client would not have been loaded properly. ("Could not find resource locally: gfx/loginscr")

Try clearing Salem from Java's cache. This might fix the problem (bad download), it might not. There are a couple of other possible fixes, but this is the easy one.

One other I can think of has to do with network security software. This includes any built into your network router. Make sure Salem (or Java apps in general) are allowed. Making sure the right ports are open may be necessary (TCP 1871, UDP 1870).

How do you clear Salem from javas cache?

[MagicManICT]

Open up the Java control panel (depends on OS). On the "General" tab, click the "View..." button. You can clear out specific apps here. If you click "Settings..." you can clear out all temporary files.
