"parsing "(a" - not enough )'s" pop-up. Error linked to List of Words (QA Checker 3.0)

Dear Community,

It has taken me a while to figure out why I was got this pop-up when trying to confirm segments in my translation but I finally did it! I do not know the solution though... maybe any of you has the same problem:

It started this morning with my previous Studio 2014. Every time I wanted to confirm a segment I would get a pop-up saying ""parsing "(a" - not enough )'s" and the segment could not be confirmed (and then not updated in the TM). After a few hours playing around I realized that this only happens when the option List of Words (of QA Checker 3.0) is active. If I uncheck this option I do not have any problem... but I want to use my List of Words of QA Checher 3.0.

I have also tried to deactivate the option until having finishing the translation (and that works: I can confirm segments) but then I can not do a Quality Verification with the List of Words at the end because I get the same pop-up message.

For a moment I thought it was a problem of my version 2014, so I upgraded to 2015... same problem.

Anyone has this problem?

Any help welcomed!!
Thanks!
