Sorry guys, I got it. I was on vacation so I just now got back to it. I disabled my virus protection when originally trying to get it to work, but as it turns out just disabling the antivirus does not disable other features.
For Bitdefender users, make sure to add an exception for your trainer .exe to both the Antivirus and Advanced Threat Protection features, no need to completely disable either, and the trainer will not stick on the splashscreen. Thanks for the help!
Anti-Virus is the Number 1 Tip on the Troubleshooting page, too. 😉
