Simplest solution:
You could try System Restore to the date Java was working for you.
OR
Uninstall Java, RESTART COMPUTER, install Java, RESTART COMPUTER
Most of the times, it works.
JRE 7:

JRE 6:

OR
Check java is properly installed as follows:
- Look inside folder "C:\Program Files (x86)\Java" or "C:\Program Files\Java"
- Does it have folder "jre6" or "jre7" or "jdk6" or "jdk7"
- Is Java added in the "Default Path" list?
NOTE: I believe Simba just needs JRE, not the whole JDK. However, if you install JDK, JRE is also installed with it.
