hi. I want to report a case of incompatibility between admin user access frontend and jseblod cck

my site is asapiens.futurasys.com and now I just installed jseblod cck, I had a blank homepage. so I decided to set the maximum level of error reporting. and in fact I read in homepage " Fatal error: Can not redeclare class class_mod_aua in ... / modules / mod_admin_user_access_frontend / mod_admin_user_access_frontend.php on line 21"

do You know this problem?

not heard this before.
Thats a lot of downloads:
www.jseblod.com/download.html

What do I need to install to reproduce that error?

jSeblod CCK 1.7 RC3 [New Install]

this is the version.

which of the downloads is that?
