Since using the ehlib, it should use the database, because it's been so long since I had no XP system, so not sure what is the control of reason or the reason of database
But ehlib the chances of that problem, you can also take a look at your part of the database connection, or do a simple small program to test himself,
Again do not move the development environment on Windows 7, recompile, also not line, you can debug on Windows 7 will know why
