It already happened two times. Once on our Pilot system and now on our test environment. On our Pilot we had the luck a Consultant was over doing an implementation and the problem came up during his visit. I completely forgot to document how he solved it.
Now on our Test env. I installed all the adapters and software and next thing after restarting the server PUFF! is gone.
I cannot reinstall it because the systems says it is already installed.
I cannot deinstall it because the deinstallation gets always stuck in the beginning (some Java problem).
I cannot use it because it is ivisible.
We had the exact problem before and I already wrote to the consultant who during his staying experience the same problem (BUG?) and while I get any answer maybe somebody had already this thing going on and can help ?
