Is it possible that a file with 100 codes in it is too big and would cause it to crash?

The codes I needed are in this document:

I ended up just manually copying from notepad & pasting them into the HEX editor, then dragging onto the buttons. This sucks because it renames the button to "hex data" every time you do this, but it works, sort of...

After spending half the day doing that I learned that Cambridge Audio uses toggle bits in their codes. Pressing a button on the remote twice is supposed to send out an alternate code so the pure hex code doesn't work reliably! I think there is a way to implement this in MakeHex using the Define T parameter but I don't know.

So I started to use Learn-2. The problem I have with this feature is there are options for repeating codes that I don't fully understand yet. Also success for the second learn seems to depend on how long I hold the button. So much for my day off!
