mxit doesnt load anymore in the mpowerplayer. java downloaded a new version of mpowerplayer and when i click on the mxit, it says that a problem occured. please help!!!

Indeed, MPowerPlayer tried to change to MXit V5 on the MPowerPlayer catalogue, which does not work.
(When you run MPowerPlayer and go through the games/applications list and choose MXit)

* Read here how to get it working on your computer again -> mxit.defza.com/get-download/pc-computer.

The simplest way (to use MXit Version 3) is to use this link: webstart.mpowerplayer.com/www.mxit.co.za/wap_old/mxitk/mxitk.jar.jnlp
