Need help with J Another Xsell mod:

My systme: ZC 1.3.8a, with Xsell mod and Xsell Advanced mod, and Cart Usell/Xsell Mod installed. Works very well.
The system also has Module Manager installed.

After I installed the latest
Just another Xsell Mod. (replacing most of the old files with new files, I dont see any SQl patch come with the JAN Xsell mod, so I assume there is no DB modification)

Problems:
1. I cannot see
Admin->configuration->cross sell
(I have checked all thrid party modules in Admin Profile)
2. in the Catalog/Advanced Cross Sell:
I got this:
Product Cross-Sell applies to:
Product XSELL_FORM_INPUT_TYPE(s):

3. I go to Tools/module manager
I got this error:
Fatal error: Call to undefined method yclass::init_template() in /home/gotwovie/public_html/adminspace/module_manager.php on line 14

ANy one has any idea? please help.
