Need to convert an OST to a PST file

I have a OST data file used in outlook, i used to be connected to an exchange server and was using it in cached mode. How on this devils earth do i change this damn file to a PST so i can change my user to a workgroup. (*.PST file)

thanks for any help!

Unforyuantly i only have the OST file. All the programs cost about $200 and the trial only recovers about 40Mb out of 300MB.

I will keep looking, anyother ideas?
