acrobat XI Serial Number Issue

[Michael260412223wwb]

Serial Key is not validating in the application, saying that it has been revoked.

How should I use my serial key ?

If it's been revoked, it's because Adobe have found something odd (such as, the seller not having the rights to sell that license). You can try contacting Adobe, but Acrobat XI is long out of support now.
