Handcent smileys

I liked everything except the fact that people would complain to me that photos I sent would disappear after a certain amount of time, whichever had happened before. However today just randomly the app decided to delete itself and even though I have redownloaded that app., I keep getting a warning that it will kind of damage to my phone, and I can't open the app.

I've had handcent sms for many many years now including the extra wallpapers, smilies, all downloaded and I've NEVER had any problems what so ever, during my mobile contracts and changing my mobile from time to time I've never had any trouble with any of the services...these guys who design this app I have to say are awesome..they deserve more recognition than they get 10/10

I love this app, had it for many years. I know there were some issues with the app a few days ago and although it's back to normal, I'm wondering how/why the emojis are so huge when I send/receive them in a text? How can I get them back to normal size??
