2 dead Doser 2.1's after GCC update

Hello,

I haven't updated my gear for a while and decided to make a day of it and start updating equipment. GCC on my PC was updated to V1152, the Profilux 3 is now v650. The dosers would not connect to GCC, so I performed the FW update via reboot button and FW flash tool. I updated the two SA Doser 2's to v154 and the logo lights wouldn't come on. I then tried v153 and the lights came on (pulsing purple and to blue on one, only purple on the other).The buttons to manually dose do not work. The Profilux 3 and SA dosers are not visible on GHL Connect.

All I want is to be able to log onto the Dosers with GCC so I can adjust the dosing parameters. Any help would be appreciated.
