nconvert memory address error when using -l filelist.txt

[xnConverter]

I am getting a memory reference error from windows 2003 server. At instruction "0x00408d48" referenced memory at "0x00000000". The memory could not be "written".

Here is my command line:

nconvert -npcd 2 -size 256x256+0 -ctype grey -corder inter -out jpeg -ratio -rtype lanczos -rflag orient -resize 260 260 -l filelist.txt

Without the filelist parameter, testing on one file like this:

nconvert -npcd 2 -size 256x256+0 -ctype grey -corder inter -out jpeg -o new_%.jpg -wmfile "DVWM2.png" -wmflag bottom-left -ratio -rtype lanczos -rflag orient -resize 260 260 1127.jpg

Works. It creates a new jpg file out of 1127.jpg and adds the watermark contained in DVWM2.png.

I just need this program to work with a whole directory of over 14k of files. The param -l filelist.txt would do the trick.

Please help!
