Hi Simon,
The error message:
> Caused by: java.lang.UnsupportedClassVersionError: com/sap/sdb/tools/ui/application/ApplicationPlugin (Unsupported major.minor version 49.0)
usually indicates that a wrong Java Version was used to run Database Studio. Database Studio needs Java 1.5 to run.
Please check your Java installation and your JAVA_HOME environment variable to point to the Java 1.5 installation.
Cheers,
Daniel
