trying to burn 725mb cdi file

i am trying to burn this file using disc juggler. i open it in there and it won't let me press the record button. i have it set on 1x and only have Overburn CD checked. the default was set to open on mode 2. is all that correct? i tried checking other boxes and everything to see if it would let me record but it wouldn't work. i have a plexwriter 12/10/32a and am using a cracked DJ ver. 3.0076......... i have succesfully copied a music cd on this version. any help out there?
