Aes Encryption not working

I have no idea whats going wrong here. Everything works fine and it loads, but the 'encrypted' data is the same as the original data. No encryption had been done.

if (entry.type == stype.file)
{
    aes.IV = aes.Key; //for now just testing..
    byte[] startData = File.ReadAllBytes(baseDir + entries[i]);
    aes.CreateEncryptor(aes.Key, aes.IV).TransformFinalBlock(startData, 
                                                             0, 
                                                             startData.Length);
    entry.data = startData;
    entry.data_size = (ulong)entry.data.LongLength;
    ulong eSize = (ulong)(29 + (ulong)entry.name.Length + entry.data_size);
    total_size += eSize;
    entry.entry_size = eSize;
}

entry.data is the same as the original startData. Is TransformFinalBlock not encrypting the startData?

TransformFinalBlock returns the data, it doesn't encrypt the input inplace.
