Hi Mike,

I did not try that, I definitely would give it a try the next time round, thanks. Unfortunately, I had to re-import all my data again after deleting them to upgrade.

So it seems like a common problem with XC5 customization then?

That's unfortunate, I hope they find a way around this restriction soon because otherwise it really defeats the purpose of having XC5 to be modular and upgradable.
It would very likely affect the number of people who renew their upgrade subscriptions too so they should take this pretty seriously.
