Acrobat Reader ne fonction plus

I pay for Adobe Acrobat to sign documents, and it works fine on my desktop PC. However, I'm going to use my laptop this week while traveling for a client's business, and it won't recognize my digital certificate; it's asking me to sign again. I'm not going to do that because my digital signature appears, and Adobe Acrobat is hindering me. I'm going to lose work because of weak, poor software that has been giving me problems since 2021. I pay 139 Brazilian reais every month for it to hinder me and ruin my work with companies that now require digital and certified signatures.
