Hi
My apologies.
I might not have checked my email or B4A recently, but i do check my paypal regularly.
Make sure to email/pay to:
rootsoftllc@gmail.com
Normally if you have paid, you should receive the files within 24h.
If you have paid and didn't receive the library files,
please message me the transaction id and your email to the above adress.
Again my sincere apologies.
Kind regards,
Tomas
Edit:
I see that my contact mail on B4A is my previous email that I don't check, this might have caused this issue.
