Help with burning bwt

Im kinda new to bwt files and I was trying to burn an image onto a cd and was told blindwrite would let me do it. When I go through the cd writing wizard, I get to the point where I select the cd-rom image and I select the appropriate bwt file (for all I know) but the “next” button is still shadowed out. thanks

here is more of a description: in a folder I have .nfo, .bwa, .bwi, .bws, and a .bwt file. When I open Blindwrite, it asks for a bwt file and I provide the one I have but it doesn’t allow me to procede
