My transition from T5 to Genos was relatively smooth. Transferred all my T5 registrations, external multipads, external styles, etc.
No problems with registrations. However, I had a chance to read lots of posts on this forum before making my transition and decided to do as many did . . . . USB stick
At the beginning i had a couple of registration errors and some level of frustration, but then realized that it was mostly me not being familiar with the new navigation screens.
In some cases, i had to re-work some registrations to adjust for new volume, setttings, etc. I am still re-working some registrations but no major problems.
Hope you fix your registration problems soon.
