"SED: TECH253087 Decryption blocked. The file that you are trying to decrypt is not secure because it is not encrypted using SEIP (Symmetrically Encrypted Integrity Protected) packets."
I'm a home user who recently upgraded Symantec Encryption Desktop (SED) to version 10.4.2 MP3 and now can't open any of my many previously created PGP Zip files. I found the TECH253087 tech article that says there's a solution, so contacted support but was told they can't help me at all because I didn't buy a license for the product.
So is Symantec is offering no solution to this problem for long time users of this product for home use, leaving us home users with encrypted data that's no longer accessible?
There must be something Symantec can suggest, or is Symantec saying home users must now pay for a software licence to get their data back (ransomware)?
Any thoughts or suggestions are welcome.
I'm running SED on Windows 8.1 Pro x64 OS.
