have Chomp SMS and now getting 2 sms's


I just got the Incredible S a couple days ago and love it, glad I dumped my Xperia X10i for this.

I have ChompSms installed and every time I get a message I get it from Chomp and the phone book, how do I stop this?

Also, I imported my contacts from my sim card that I brought over from the Xperia and they show up fine and are useable but I can't move them into groups, when I go into a premade group (Family) and click to add a contact none of my contacts show up, how do I fix this?

Any help would be appreciated
