Ah I understand what you mean. Yes the plants I have prior to V5I had problems with V5I, so E-On said to use the versions that were on the CD. If I remember, V5I asked for the serial numbers (which worked), but I haven't purchased or converted to the C3D versions as far as I am aware.

So maybe what I am doing differently is that I am adding a collections/shortcut to my V5I plants which seems to work - maybe that is the difference?

I'll double check just to make sure.

Thanks

EDIT - Ah you're quite right - some of the old items say Unable to read, so presumably as long as you have an order to show your original purchase (in your account) then you should be able to get hold of the C3D version.
