Turn off your anti virus and then try to extract it, that usually the case, also they haven't updated it yet and probably won't for awhile. As seeing people cannot use the injector responsibly, odds are, they update it, and then its a complete repeat of what happened before. Sooner or later, there will be no more loopholes.
Though a suggestion would be to just not inject very often and to inject units and spheres that aren't exclusive. Gumi took the time to ban thousands of accounts that were pretty obvious cheaters and suspicious accounts. They are still working to unban legit accounts. I suggest you read earlier posts in this thread seeing many do not know how to do that. (Not going to imply anything)
One last note.
Don't be that guy...
