"java.lang.SecurityException: The provider BC may not be signed by a trusted party" error

This shouldn't happen. Something has probably changed how Envelopes is started up. If not, please send all the files and folders in the logs folder of your Envelopes data folder to support@tigerprivacy.com. Be sure to replace any private information in the logs with asterisks first.

For experts:
You are probably using Bouncy Castle Crypto with Sun's java security manager. Tiger bypasses Sun's JCE by using the GNU Crypto java security manager. Bouncycastle.jar must appear at the beginning of your boot classpath. With the sun jvm you need

-Xbootclasspath:p:lib/gnucrypto.jar:lib/bouncycastle.jar:lib/javamail.jar

on the command line. For a more complete example see the ant build.xml for Envelopes.
