Premium Plus version showing as Free version with watermark

I purchased the Premium Plus version. I was on a train and did not have an internet connection when I started it up and accidentally clicked on 'continue to use the free version'. Now that I have an internet connection, FlashEff won't log into the Premium version and still displays the Free warning and watermarks. What do I do now?

Just log out from the panel(menu->sign out) and the login again by using your premium account. Everything should be ok after doing that.
