Using Arabic Fonts in Curves..

Dear Sirs,
I've been using Corel DRAW for some time now, and although my use is somehow limited, I learnd some stuff, and to say the truth, I find the program interesting, but my problem is that I use Arabic fonts for graphic perpuses.
Till now, my way is to creat the paragraphs in word.doc, print it in PDF, save the PDF to *.ps (postscript) then import it to Corel (in Curves), and it is actually working great, but I only have two arabic fonts to use. All other fonts are rejected by Corel.
I already installed the fonts in Corel, and yes they are installed in Windows.
Please I need to enlarge my choices to some other fonts (arabic), please can you tell me how to enable these fonts through the same method I'm using, or if there is any other method to have the paragraphs written correctly in Arabic in a Corel Page.

I'm using Windows Vista Home Premium and Corel DRAW X3 English.
