Did you have any of trhe older plants that were bought before the c3d store was in existance or were all the plants you had no problem with the, default vue plants and not the addons that had to be bought.

This seems to be where the problem is with older plants bought from e-on before C3d.
We got the plants and a serial that has always worked with Vue 4.5 Pro and Vue 5 Inf when loaded manualy.  When you click on the plants folder it then ask for the serial we received with the plants.
