Can’t replicate that here. If you haven’t done so already, please first try both troubleshooting options that appear in the ‘Attaching to…’ dialog after a while, i.e. installing a hook helper and switching to alternative hooking. That can often resolve hooking problems without getting to the bottom of the matter.
If that doesn’t help, please check for potential conflicts with other programs on your PC. Hooking issues almost always are caused by conflicts with programs that also hook into games. The trouble shooting guide on top of this sub forum has more details on the matter.
