I think there's two issues at play here.
I can log onto the FSM page using my old user name and password. I have the "keep me logged in" box checked, but it does time out after I've been off the page for a while.
The second issue, I think, relates to Kalmbach's overall customer database. If you click on "update account" it requires you to log in. If you select "log in using your email and password", it will reject your existing password, even though you are still logged into the FSM page.
The next thing I tried was the "forgot my password" option to reset my password. Upon entering my email address and reconfirming, it returns a message "Please enter a valid email address" Yet this is the same email address which I used to log in to the FSM page.
