It appears that TDBAccess is not compatible with .NET 2.0. I will release a fix as soon as possible, but for now you’ll have to use .NET 1.1.
Updated GTA: LC page. Added the latest source for the launcher. Despite the release of GTA: SA and GTA: LCS, Liberty City project is still alive and well. New version will be released shortly and for those who haven’t tried it yet, I highly recommend to visit the official “site”. It’s truly amazing how one game can be so completely transformed into another (for the record, GTA: LC is a mod for GTA: Vice City).
