If at all useful to anyone, I have noticed that the Align tool seems to have a bug whenever you connect segments in a way that connected segments "cross over" other segments. In my experience, whenever something like the below happens, importing to the memory is impossible. It may cause what the OP is experiencing as well. It might be worth a try to try and disconnect those. You could edit segments manually (copying and pasting source and target) to avoid them crossing over other segments.

Hi Jose Fernandez

I can't confirm your above observation. I use the alignment tool a lot and I have a lot of crossed over segments (InDeSigh!), but this never prevented exporting into a TM. I did experience a "too complex" error when many segements are crossed in very intricate ways and then the file is realigned. The realign function seems to be able to cause alignment corruption in some cases.
