Hi,
This has happened to me too. We need to change the local_policy JAR files for stronger crypto and yet if we replace the two JAR files in C:\ColdFusion10\jre\lib\security, then CF Admin does not work and we also get errors elsewhere on our site.
Please Adobe, will you respond and tell us how to update the policy files? We need this to run PayPal payments on our site urgently.
Regards,
Mark
