Someone Cracked My App - Help Me Learn How They Did It?

Create a VM with zero access to the rest of your data, install Xojo on it and a copy of your project, use a build script to replace the dll at run time and step through your code.

If you install Sandboxie, you can install and run an app in a sandbox and observe it working, it is specially useful to observe post mortem results like windows keys changes, dropping hidden packed dlls as Sandboxie shows what it changed. Then, after inspection, you just throw the sand-box away and nothing was changed in your system.
