Ok? – DLTTR Review

I got hacked and the hackers tweeted some rather nasty things and I needed to delete it all so I went ahead and bought the pro version for $2.99 which is a bit pricey to me. But anyways, I guess it does what it's supposed to do. Except it won't actually let me delete all my tweets. No matter how many times I select delete all tweets it leaves me with 7k tweets left and I have no clue what to do!
