    • Maybe you're using too old a JRE

      By Karl Freburger 1 decade ago

      You may be using an older JRE (say, 1.4). I'm not sure what version is required to run GooCalSync; I think I used a Java 1.5 JRE when I tested (I'm waiting for time zone issues to be fixed before I really use GooCalSync)
