Question: As a beginner I am having hard time and sorry for this basic question.
I have bought some vector from ShutterStock and while removing the background layer, I get some black gradient in the edges of the sparkles!

For easier understanding, please see the image below.

How do I get a fully transparent image of the shining frame. [I have the layered vector file of the image]

Answer: 
There are many suggestions to this but I think none of them will get you where you want. If you intend to use this flare somewhere else you don't have to convert into a transparent object. All you need to do is **copy and paste** it in front of the work you intend to **apply the effect** and make sure that **transparency mode** is set to **screen.**
Asim, of course it is.

Either those elements are locked, grouped, a clipping path or a compound path.

So unlock everything. Perhaps the frame is a group onto itself and it can be removed or locked leaving everything else to be deleted. 

There are two different arrow-selectors ... one selects groups, the other individual paths.
