Blur Plugins

I have a problem blurring text in CorelDraw:

1.  I put text on page.

2.  With the text selected, I go to "Bitmaps", then "Convert to Bitmap".

3.  Next I go to "Bitmaps", then "Blur" (which is highlighted), then I try to select one of the nine blur options, they are there but not highlighted, therefore I can't select them.

Help says to download the blur plugins.  I have searched my software disks from X3 and X4 and can't find these plugins.  Can't find them on my harddrive either.

Can someone please help me.

Thanks in advance.
