WPBakery registered to an old site, I can gain access to

I purchased VOIP - Telecom and cloud services theme a few years ago and all was great. I set up a test domains on my old hosting platform and reinstalled the theme. I recently moved hosting providers and no longer have access to the old domain. My existing site no longer works correctly as it looks like the WPBakery licence is registers to the test domain on my old provider. I cant get access to deactivate it so I can use WPBakery on my current site. Can any one help me please
