Frostwire not staarting

[Guest]

Hi Everyone,
I am new to kubuntu and just love it. I have a problem with frostwire.
I am running Kubuntu 9.04 and Frostwire version 4.18.0. I downloaded debi package and installed through package manager. I do have java installed. The trouble is when I try to start Frostwire, I get following message

FrostWire version 4.17

Linux v. 2.6.28-11-generic on i386

STARTUP ERROR!

I am not a programmer so will need all the help.

Thank you in advance for any help.
