Test holder stopped working

I bought my Clearblue ovulation test kit some time ago, I really loved it and got pregnant thanks to it (found my peak fertility day) and since I was pregnant, didn’t have use for it and it stayed in my drawer, dry and safe. However, after I had my baby and 6month later I decided to start using ovulation tests again to see how is my body doing with ovulation and etc. I was using birth control that stopped my period so I had no idea if my body started it’s normal cycle yet or not after I stopped my birth control. But unfortunately when I took out my test kit holder was no longer working. I tried to insert wake up stick to see if it would help, but nothing.. and I still have at least half of the tests unused.. what should I do? Can holder be fixed or something to work again? Or is there a way to get new holder itself?
