Got two cartridges, one worked, 2nd didn't work. Only HALF worth it...

Ordered in January, and kept the cartridges sealed until I needed to use them. The first cartridge worked fine, but I attempted to use the second one in November (still sealed) and my printer wouldn't read the cartridge. Literally nothing would work. I tried troubleshooting my printer and all manner of test prints, etc. After about 20 tries, I just had to remove it. I'm totally disappointed...
