Is SPB Mobile shell incompatible with the 6.5 upgrades?

After installing and doing a reboot all I had was a picture of the ocean with a Seagull flying around. I had E-Natives assigned to my side button and I was able to clik the home button from there to get out of the shell. But everytime I try going into SPB nothing works, no icons and no way to escape the app without going into E-Natives.
