That software is supposed to fix Error 0x80070003. And it doesn't. Please give me your support phone number.
The developers offer you the possibility to contact them through the contact form available on their website, but you can use the phone as well to get in touch with them. Use the details below to either send an email or call them.
I also recommend reading the FAQ page where various issues are explained. ,
Will not fix the error anyway. I will just ask for a refund.
