Don't worry, you're not alone!
It happens to me too all the times.
I just can't remember how do enter the test mode on my Affinity too. Every time i have to call my friends or get the user guide. 10 minutes after that, I can't remember anymore.
Try Gingko Biloba, dear. At least in my case, it works great for the problems Dr. Rolón or Dr. Rovilson can't solve. LOL
