Instagram

I side loaded Instagram like two weeks ago.
Been loving it!
Had to do a phone wipe two days ago for an unrelated problem.
Now I side loaded it again, it doesn't work.
I tried everything.
Need some help please.

I didn't the forget password thing already.
Also un installed and side loaded over three times.
Nothing is helping.
Any ideas?

P.S.
My Facebook is linked with Instagram already.
