hofxlapw issue

i'm in a gp4 hotlap league and we all have to use gp4.exe 1.02 and all laps are checked with hofxlapw now here's the problem because hofxlapw says i'm using gp4.exe 1.00 which i'm not!! and as such i've been disqualified from one comp and maybe banned if i can't solve this prob,so why is this happening and how can i fix it?????
