mere paas idm 5.18 full version mein mojood tha. maine usko takreeban 2 months use kiya. phir maine new window ki to ab jab maine usse dobara install kiya toh installation k baad error aata hai "Internet Download Manager has not been registered for 15 days. IDM is exiting". aaisa kyun ho raha hai jab k yeh full version hai. maine crack bhi chalaya hua hai.
