Application Crashes When Calling To Sql Server Routine

I have an application that manage an sql srever compact edition database it worked OK until I got the following problem:
Only when debuging the application ("Start Debugging" from visual studio). In the first call to an sql server routine I get an exception "Unspecified error [ sqlceqp30.dll ]"

My code:

this.usersTableAdapter.Fill(this.nessDBDataSet.Users);

The line with the exception:


[global:ystem.Diagnostics.DebuggerNonUserCodeAttribute()]

[global:ystem.ComponentModel.DataObjectMethodAttribute(global:ystem.ComponentModel.DataObjectMethodType.Fill, true)]

public virtual int Fill(NessDBDataSet.UsersDataTable dataTable) {

this.Adapter.SelectCommand = this.CommandCollection[0];

if ((this.ClearBeforeFill == true)) {

dataTable.Clear();

}

int returnValue = this.Adapter.Fill(dataTable); //Here I get the exception

return returnValue;

}

The Exception:

Unspecified error [ sqlceqp30.dll ]

Again if I do "Run Without Debugging" Evrything is working.

Can any one help me with this

Thanks
