[Problem ripping with pandora's jar]

I have a problem with rippping. The message is:

INFO [Thread-2] (Mp3Processor.java:39) - access file not found trying again after 1s

My system:

- XP

- Macromedia Flash Player 9

- Microsoft .NET Framework 1.1

- J2SE Runtime Enviroment 5.0 Update 7

All work apparently well except when ripping is executed. Somenone know resolve this problem?

Thanks in advance.
