Cannot launch/startup HO version 6.1

[amss1976]

Hello everyone,

For some months I have not been able to launch version 6.1 of HO.

When it gets to "Initialize Database" it gives a Start Up error window with the following ingormation:

java.lang.NullPointerException: Cannot invoke "java.sql.ResultSet.close()" because "rs" is null

Any idea of how to solve this problem?
