same here on those two DeJay and minidvd 31, so the first 25 submit counts not the time.
hehe
its easy to change g to G but here are a temporary fix
simply rename all your replays to .Gbx like this.
1. use notepad write
REN *.gbx *.Gbx
2. save file as:
3 select save as type: "all files"
4 name file as:
Gbx_fix.bat
and place the .bat file where your replays are and start it
5. done
all replays are now .Gbx
and when the replay submit works you do
ren *.Gbx *.gbx
