I have Adobe Professional 8.0 I removed it from an old lap top, and re-installed the s/w on my new laptop and registered the software.
Since then, when I attempt to use my digital signature. I get the following message:
Platform Exception
Key not Valid for use in specified state.
Error Code: 2148073483
I'd really like to use my digital signature again - can anyone help?


Thank You!!!


I didn't find the right solution from the Internet.
