Question Titanium Backup Freezing During Backup EVERY TIME

As the title suggests, every time I make a backup using Titanium Backup it seems to freeze on around 20%.

I know I have plenty of space on my SD card, but it just hangs and I have to Force Stop the process.

Anyone else having / had this problem??
