arduino fails to load [solved]

when i try to

  1. start arduino 17
  2. get the splash screen
  3. then it freezes for 30sec
  4. get message box

i think is has something to do with the rxtx,
this only happens after i have a successful first connection with the arduino.
nothing but a restart will make it work again (once).

tried:
troubleshooting guide.

java version “1.6.0_17”
Java™ SE Runtime Environment (build 1.6.0_17-b04)
Java HotSpot™ Client VM (build 14.3-b01, mixed mode, sharing)

windows xp sp3

UPDATE
well it was a collsion with nokia pc suite.
i disconnected the phone, which was identfied on COM3 using usbser_lowerfltj.sys driver, the arduino IDE works again.
