SQL Server 2008 app date time format is not like the one set on regional settings

Hi guys , I have been experiencing the following problem, Just got a new laptop with win 7 pro and installed MSSQL SERVER 2008 , I have set my laptop's Regional Settings to Greek , which means that the date format is DD/MM/YYYY.
When I connect to sql server via an ERP application the date format shown is MM/DD/YYYY.

I double checked my regional settings , the Locale settings is everything set to greek and the date formats are the expected ones , I even changed the default language for the sql server login to greek , but the problem remains. I have done this installation type 100 times on XP and never had such a problem.
Do you have any Ideas???? I am sure it is not the application because I have found another laptop running win 7 and the sqlserver 2008 and the same erp application with no problem , I checked all the settings on the other pc and are identical with mine.
I really can't figure this out.

I am not sure what your ERP application is doing exactly but have you checked the language setting for the login that the application authenticates to SQL? This can affect how dates are interpreted by SQL.

if you mean the sql login I use the sa user and have tried using the language to english , british english , and greek. None of them worked
To eliminate the application as the cause of the issue, could you network the two computers together and then reconfigure the working ERP application to talk to the newly installed SQL Server?
