Admission deferred after visa stamping

Hi, I got admission for MS in Computer Science at UIS for fall 2015 term. I got f1 visa stamped in July 2015. However I could travel due to some personal reasons. Now I have new i20 from same university for spring 2016. My question is about my current visa validity. Do I need go for visa stamping again. Even though I have confirmation from USCBP and US consulate (that I can travel on same visa), I am still confuse about 5 month rule. Does anyone got some information or experience with similar situation?

Thanks

Your stamped visa is valid. At the port of entry, they sometimes ask about your correspondence with school about deferment. Otherwise there is no problem.
