Plugin conflict error when logging in [Coursepress x Membermouse]

Hi,

I started to face recently a problem with my website, I have Coursepress Pro installed working with Membermouse for membership

the problem is:
when an user that has his membership expired should be redirected to a page that says ¨An error occurred when you tried to login, check your membership etc...¨ instead I'm getting an AJAX error, I've been trying to solve this with Membermouse because first I thought that it was its problem, after some days trying to solve this the support team came to the conclusion that the problem is a conflict with Coursepress (you can see the video screen recording ... http://www.screencast.com/t/QkkL47gHK )

I will grant access to Coursepress support team to check this out

hope to get any answer to solve this problem! thanks a lot!
