heres what you do(before installing dsl):
go to C:Program files/infogrames
there should be a folder called "robot arena"
right click the "robot arena" folder and copy it
paste it in the same folder... takes some time
the new folder will be called "copy of robot arena"
rename it to "robot arena-DSL"
then install DSL in that folder

I am hoping to have dsl-2.0 do this for you.
