ERROR CODE 630

This so frustrating I just repurchase Turbotax 2019 because I kept on getting error code 630 I spoke with Turbotax support and they said that they could not help me because they did not had license code anymore available for 2019.  I repurchase the software and still getting the same error code. I followed every step uninstall and reinstall, renaming and I still get the same error and have not been able to get access to my old files for 2019.  Does anyone have other solutions.
