Veloeclipse seems to be compiled with JDK 1.6. You are most likely running your
eclipse ide with a Java version below 1.6. Therefore the
UnsupportedClassVersionError. Try running Eclipse with a JDK version 1.6. 

If you already have a JDK 1.6 installed, put these two(!) lines at the 
beginning of
your eclipse.ini:

-vm
C:/path/to/jdk-1.6.0_16/bin/javaw.exe
