Ultimate Zip Xamarin component. Trial expired exception with licensed version

I installed the Ultimate Zip component (v.6.1) as a trial in my iOS and Android apps. After running a few tests I decided to purchase the full version, which i did from the 
Xamarin Website with the invoice number 1071.

In Xamarin Studio the trial component was uninstalled from the projects and then, the full version of the component was installed. Now, in a production enviornment the app is generating the next exception : Your trial UltimateZip is expired. Please contact ComponentPro Sales Team at sales@componentpro.com

I have tried the following with no change:

1. Uninstall both components from the solution projects (validating that no dll or other files are still referenced)
2. Clean the whole solution
3. Delete bin and obj folders
4. Uninstall the trial version of the component from my iMac by deleting the UltimateZip-trial folder from the /Library/Caches/Xamarin/Components/ folder
5. Uninstall the full version of the component from my iMac by deleting the UltimateZip folder from the /Library/Caches/Xamarin/Components/ folder
6. Install the full version of the component in the projects, downloading it from the Xamarin Component Store
7. Compile again

I have even tried on two different Macs.

Please advice on how to resolve this since the apps are live and no longer working as it should

How did you solve it?
