It's unavoidable until the Gateway team removes all the bugs, which I'm sure are very hard to find. There has always been a chance of error with most exploits. Gateway's exploit / Launcher was much more buggy when they first released. It's much more stable now and I'm sure it isn't much of an issue for most of us. The same happened with Palantine's CFW which improved the existing problems with GiovanifY's CFW. However, that is much less stable than Gateway's Launcher.
