I have selected the library Lightware, and it moves from left to right box but after I press OK and the system have done syncronisation, there is still no Lightware in my list in Stardraw ?

I have just tried to select another manufacturer not loaded before, and this company shows up.

I have used Lightware before this was in the manufactures list, so I have a Lightware in my user defined Products list, can this create a problem ?
