When vorpX can’t hook into a game e.g. because of some conflict with another program on your PC, it ususally displays some trouble shooting options in the “Attaching To…” dialog after a minute. Try to install a hook helper or switching to alternative hooking when you see these options.
If you don’t see the “Attaching To…” dialog at all or the trouble shooting options don’t help, you have to resolve the actual conflict. Hookung issues almost always are caused by some other program that hooks into games in a simailar way as vorpX. The trouble shooting guide on top of this sub forum has more details on the matter.
