Conflict with Joost?

[AlCapwn]

When running Joost, I cant get Apache to run. I think some sort of port conflict. Here is what apache_start.bat gives as output:

C:\Server>apache_start.bat
Diese Eingabeforderung nicht waehrend des Running beenden
Bitte erst bei einem gewollten Shutdown schliessen
Please close this command only for Shutdown
Apache 2 is starting ...

no listening sockets available, shutting down
Unable to open logs

Im using Xampp lite 1.6.0 on Windows XP Home Sp2.
