Coll won't find its files in M4L

Hi!
I'm trying to build a device that uses 3 different lists and I want to load each one into a different coll everytime I open the device.

However, every time I try to load the device in max for live, it doesn't work, and when I open the patch and unfreeze it, the max console sends me "coll: can't find file chords1.txt" as error messages.
The weirdest thing is that it only happens in M4L... When I open that device in Max 8 (Standalone) it works fine and it finds the files for all the colls.

I thought that freezing the device would help to keep the files it needs to operate, including colls. But that is not working.
I have the lists files (the .txt files) and the device in the same folder. That is not working.
I thought that writing the file name as argument in coll would make it load that file everytime the device was opened... for example: [coll chords1]. That is not working.
I tried with a loadbang connected to a "read" message with the file name (read chords1.txt). Not working.

The only solution I have found so far is to manually open and load each list everytime I load the device.

Any idea about why this happens?
Should I save the patch and its .txt files together in another place?
Is there anyone else having the same or similar problem?

Thanks!
