Recuva stops at 45%

I wound up deleting over 4000 pictures of my grandkids on my phone's SD card. I am running the 1.53 version and paid for the professional version. I have tried to running Recuva but it hangs at 45% and it shows it is still in Stage 1 of 3. I started last night and let it run all night and checked in the morning and it was still hung. I let it run all day while I was at work and came home and it was still hung at 45% what is causing it to hang at 45%? I tried the recover what it did find at 45% and that hangs at 53%. I am running Windows 10. Any suggestion on what is wrong? Any help?
