Linux: When I start the program, only a blank window appears

There are currently two known reasons for this problem:

• the "wrong" JRE (Java-Runtime-Environment) is used to start jAOLT; you have to use Suns JRE or the openjdk-jre (either version 5, 6 or 7)
• you are using java 5 and Compiz-Fusion which does not work together; to solve this, simply install java 6 or 7

I got the error: "The token does not exist, the user must complete the Auth & Auth sign in process to generate token."

As said in the error-message, you have to:

1. click on the Click-button
2. sign in (eBay)
3. agree the share of the data
4. enter the security code
5. click on Authenticate

I got the error: "User must have a store subscription."

This error occurs, if you are trying to fetch the shop/store-categories of your personal eBay-store which does not exist.

Error: Your application has exceeded usage limit on this call, please make call to GetAPIAccessRules to check your call usage.

Update to a version larger or equal to 0.4.4 and re-auth your eBay-Account in jAOLT.
