SIRIUS 3 is not longer supported

We found a major bug in the web service of SIRIUS 3 which can also affect the stability of the new SIRIUS 4. Therefore we decided to shut down the web service of SIRIUS 3 immediately.

Please contact us ( ed.an1537562004ej-in1537562004u@sui1537562004ris1537562004) if you need to finish work that can only be done with SIRIUS 3. We will try to find a solution then.
