I recently used dynamiclink from Adobe Premiere CS4 to Adobe After Effect CS4.
And It worked fine. But now after I closed the project (and saved)
that file I was working on after effect shows Media offline in Premiere.
There aren't any details in your post about your system to make an intelligent diagnosis. But you should know that Dynamic Link may be a great idea, it doesn't work very well.
Premiere and After Effects are obviously two different applications, and do different things. To make matters worse, Adobe bought both Premiere and After Effects from two different software developers, who had two very different ways of organizing and working with data; in the end, that's all there is to video: a stream of data.
The Adobe engineers gave their best effort to reconcile these two very different ways of working with data, but there are still certain things to just don't work properly.
