Starting Mobilesalesfailed - High

I am facing the same problem as Mr Balamurugan C , the only difference is i have installed MSA 4.0 in my machine for practice/learning purpose.Here i dont have a CRM server but i have some workgroup server.

The problem:

"I have make some changes in MAS. After generating the Object with Option (Mark Dll in Business Object and UI), I cannot logon to MSA. It is giving the following error.

UI_CORE_APPL_LUNCH_FAILED_STA - Starting Mobilecsalesfailed

What could be the Issue?
