Notes 8.5.2 and Sametime

Since 8.5.2 was release last Tuesday we upgraded a number of users from our test group. All is working and users are happy with the speed. One problem we run into is that we can no longer login to Sametime with the Sametime embedded client. Now I know that 8.5.2 comes with the build-in 8.0.2 sametime client but so did 8.5.1. Is someone experiencing the same issue? The Sametime release is an older Sametime version 7.0.
