This is a self-help forum and you really should try the all the things on that list. 😉
Many of the issues with the Add Media button have been javascript related. Try enabling the Javascript console on your browser as explained on this post.
If you do see a javascript error on the console when you try to load/see/use that Add Media button then please let us know here. There may be some more advice we can offer you to help you fix your problem.
