taghycardia's web store is undergoing a makeover...
In the meantime you can:

Get the Free edition: Download here.

Get the Pro edition: Due to the developments in Eastern Europe, I've been rendered unable to receive payments in any way except in cryptocurrency. If you wish to get taghycardia pro, send an equivalent of $5 in BTC to the wallet below (or use the QR code) – Tip: U.S. users can use PayPal for this, here's how. Once paid, BE SURE to contact support@taghycardia.info with a proof of payment. Shortly thereafter, I'll give you access to the program and future updates.
