Validity of VMU PG certificates?

I have done MA in English from VMU, Salem , Tamilnadu through distance mode of learning in the academic session 2013-15 from a study centre of West Bengal named Anandam Vidyapeeth which is situated in the Durgapur city. I am very anxious about the validity of my certificate which I have obtained from the university. Plz help someone. Plz provide someone some valid info .

visit the VMU site salem taml nadu then check in the list of universities recognized in tamilnadu that way facts could be known . 

Checked ugc and vmu site. Its found that the university is recognised to offer MA english upto 2013-2014 and my session was 2013- 2015. Will it create any problem?

Sir. Thank u for ur response.
