Relaunching an instance/character of a game

Hi all,
I'm wondering if there is anyway of relaunching an instance/character of a game, for example, if I have X number of instances of a game running and a particular one crashes (is2 of is5 for example), is there anyway of relaunching that particular is#?

I tried to do a search but couldn't find anything appropriately answering my question.

Thanks.

Just select the Character Set again from the launch menu and it will fill in the missing windows Simple ftw.

Doh. /smackhead.

Thanks. =)
