Encrypting lots of small chunks of data with the same key is a very dangerous thing to do and it's very tricky to get right.
Using an initialization vector (IV) is the way to go, recommend using CBC or CFB mode. Although, an IV is never supposed to be used more than once with the same key; that can leak hints about the plaintext. Where is the randomly generated IV stored for use during decryption?
