While signing for Exchange: Keystore file could Not be loaded

Hey,

I am coming from the dps forum and I am working on a panel to streamline a few processes in the authoring process for the iPad.

I want to export and sign the panel to get a zxp file.

Unfortunately, during export I get the error message that the keystore file could not be loaded.

I created a new certificate and used some other p12 ones I had around. I have java installed (1.6.0) and I am on Mac lion 10.7.4 with configurator 3.

I am sure to entered the password correctly.

Anybody any idea?
