Hi kingq803,
This seems to be a licensing failure to me.
Please try the following steps and let me if that worked or not.
Delete all the files from following folders:
C:\ProgramData\Adobe\SLStore
C:\Program Files (x86)\Common Files\Adobe\SLCache
And, delete all files from following folder except cache.db
C:\Program Files (x86)\Common Files\Adobe\ Adobe PCD
Then launch Acrobat, Accept EULA and enter the serial number again and check.
Regards,
Rave
