SAP GUI 740 Final Release

Hi, I have an issue when I launch SAP Applications ---> SAP ECC Production - UHP, when I launch it a splash window with the SAP logo appears and doesn't do anything, after a time period ~ 2 to 4 min a window pop up that Server Busy "This action cannot be completed because the "program is not responding. Choose "Switch To" and correct the problem. If I do that it will launch SAP Logon 740 and works fine, if I close the application and re-launch works fine no time waiting. However if I restart the Laptop and launch again the SAP application I have the same issue.
