Arlen Lung 0 Report post Posted December 7, 2020 Nitro Pro was working and all of sudden it prompted Trial Expired. I tried to manually reactivate and I still can't reactivate. It just tell me to check the certificate. I did 3 times already but it won't activate. Please help. Quote Share this post Link to post Share on other sites
