Having just installed this mod all seems to be working fine except with customers already registered who are within the EU but with no VAT number. Logging in these customers still shows products as VAT free. Adding new customers since the mod was added does not show this problem - it is only the old non-VAT customers.

I have searched high and low in this thread for any reference to this but can't find anything - other than a problem some time ago where this problem occurred the whole time - and I have applied the changes and that was fixed.

Any suggestions?
