Help- Cant select hl2 dm in sdk

[Brain Food]

Decided i would have a go at making a map but im unable to select hl2 dm in the sdk or even hl2, only hl2 ep2 portal and team fortress 2 even though i have both hl2 and hl2dm installed. I tried adding the command engine ep1 in the launch options but still no luck. Anyone know how to fix this?

#######Its ok i fixed it the xommand is actually -engine ep1######
