Frustrated!!

I downloaded this app a while ago and loved it! Today, I purchased a couple of the packs that are available and it worked. I tried logging into my other IG account and I kept getting an error message about Safari not being able to open the page because it couldnt be found. I then tried to log into the original Instagram account that this app was initially for, and am now unable to log in at all!!!
