NAV 500 Strange behaviour searching and programming

Hi everyone,

I am migrating a NAV 3.70 database server to a NAV 5.00 SQL Server option.

I am actually programming NAV 5.00 objects to integrate all the customizations from my old version.

Every thing was righ until this morning.

From that moment i have started to experiment several srange things. For example:

1.- The Search Button in the Toolbar from the finsql.exe doesn't work.
When I try to search anything a message appears where it seems that NAV thinks that no text is filled in the searching windows. :shock:

2.- When I try to add a new global or local variable that variable inmediatly dessapears :shock: :shock:

It is the first time that I see this situation.

I have tried the next things to solve it:

1.- Delete zup files.
2.- Install and reinstall NAV executables.
3.- Because of I started to program in a NAV 5.00 SQL Server database I have tried to make it in a database server instead of it but it is the same.
4.- The NAV database test it works right.
5.- Change NAV users, windows users, ...
6.- Compile NAV objects.
7.- Export and import NAV objects.
8.- Back up and restore in other database.
9.- Change to 5.00 SP1 executables
10.- ...

I don't know what is wrong and it is very important because we are blocked. Does anybody knows anything about this things?

Please, thank you for your help.
