"Sorry, your trial period has expired" ?

[Alexey]

Due to frequently occurred problems with unexpectedly expired trial period we want to list the most usual causes that can raise this error.
The problem may occur over one of the following reasons:
1. Your trial period has indeed expired. Either register PostgreSQLDirect .NET or remove it completely from your system.
2. You have changed the date on your computer manually. In this case you can order another trial version by mailing to support team.
3. You have changed the registry manually. Same as point 2.
4. You had registered version on your PC and now installed the trial one. If this is the case download new version from the Registered Users Area and use it to test new functionality.
If you are definitely sure that you have no concern with the above-mentioned reasons please create a small application with one PgSqlConnection component and send us all source files and compiled binaries.
