Hi all, I had a working installation of Oxygen 8.0 with JVM 1.5.9 on Windows XP. When I decided to upgrade to Oxygen 8.1 I also wanted to upgrade my JVM to version 6. I uninstalled Oxygen, JDK and JRE. Afterwards I installed JDK 6 (which includes JRE 6) and Oxygen 8.1. Since this installation I have not been able to start any of the Oxygen applications. The splash screen appears, says "loading application" and hangs at 2%. Processor usage goes up to 100% and I have to kill the process. I read in the forums that changing the JVM might help. Well, I have tried every combination of Oxygen versions 8.0 and 8.1 with JVM version 1.5.9, 1.5.11 and 6 now but the problem persists. Even the combination of Oxygen 8.0 and JVM 1.5.9 that worked before fails. What am I missing? Best regards Paul
