Instapaper itunes problem

hey

i jailbroke my iphone a couple days back so i thought i would try a cracked app, just downloaded instapaperPro v 2.2.5, after downloading i tried to add the application to itunes and itunes just does not take it, to make sure i downloaded another one and itunes accepted it but it doesn't accept instapaperPro, any suggestions?

I am not trying to sync it to my iphone just trying to add it to itunes, itunes version 9.2

Thanks

 

yup did that just then, works like a charm
