Problems with SEF Advance 2008

Hi - I just downloaded the trial of SEF Advance 2008 and installed on my J1.5.4 site with CB. Having a couple issues...

1 - SEF is consistently returning the wrong URL for one of my menu items. Specifically, I have a menu with two links, one to XMap and one to CB profile. Both links work fine initially, but once I go the profile page, the XMap link returns the CB URL.
2 - I had a page alias of "my-profile" for the profile link. SEF does not seem to work with the hyphen in the alias, so I had to remove it. Is this a known issue?

Thanks,
Philip

Please send a mail, I need to have a look on the example URLs.
