savePict and pdf problems.

I have a program created by another student which colocalises particles and saves the output into both waves (statistical info) and images. The program outputs the correct information, it can save into a .bmp correctly, but when I try to save as a pdf, all I get are blank files. The file names and folder placement are correct, they are even of differing sizes, but its just a blank white slate. I have a current, legal version of an adobe suit. Any ideas what could be going wrong?

The only relevant part of the code that I can see is :

//Save image(s)
imageCh1Name = "processedImageCh1-" + num2str(i) + ".pdf"
if(HQvar!=1)
SavePICT/O/E=-8/B=(72)/P=resultPathCh1/W=(0,0,72*xDim, 72*yDim)/Win=controlWin#micrographWinCh1#micrographCh1 as imageCh1Name
else
SavePICT/O/E=-8/B=(2*72)/P=resultPathCh1/W=(0,0,2*72*xDim, 2*72*yDim)/Win=HQ_Ch1 as imageCh1Name
endif

if(channelChooser==0)
imageCh2Name = "processedImageCh2-" + num2str(i) + ".pdf"
if(HQvar!=1)
SavePICT/O/E=-8/B=(72)/P=resultPathCh2/W=(0,0,72*xDim, 72*yDim)/Win=controlWin#micrographWinCh2#micrographCh2 as imageCh2Name
else
SavePICT/O/E=-8/B=(2*72)/P=resultPathCh2/W=(0,0,2*72*xDim, 2*72*yDim)/Win=HQ_Ch2 as imageCh2Name
endif
endif

where E=-8 should save me a .pdf according to the windows flags.
