2 Problems with my Mogul..please help

[painkillaz]

Problem 1:
Whenever I try to send a text message i get a pop-up that says: "Cannot recognize one ore more recipients or the address is not valid. Would you like to send the message anyway?" It does this even if I am sending a message to someone in my phonebook. What can I do to fix this problem?
Problem 2:
I have PocketCM for the threaded texting but it lowers my Program memory to like 3-5 MB making my PPC-6800 extremely slow. Is there anything I can do to fix this? or is there any other program that just has threaded messaging and won't take up as much Program memory?
Thanks alot
