Problem: Your application throws a CryptographicException.

The licensing mechanism uses .NET's Crypto API, so the user account running the application needs to have access to the folder in which the crypto keys are stored. Make sure that account under which you're running the application has "Read and Execute," "List Folder Contents," "Read," and "Write" access to the folder C:Documents and SettingsAll UsersApplication DataMicrosoftCryptoRSAMachineKeys. If you're using JNBridgePro to link ASP.NET to Java, make sure that the user account ASPNET (or whichever account is running ASP.NET — by default it's ASPNET) has "Read and Execute," "List Folder Contents," "Read," and "Write" access to the above folder.
