CFO (Custom Formulas)

Hello,
Has any one been able to get CFO (Custom Formulas) module to work with Journal 2, v2.3.3 template?
I purchased this module and there it seems that there is no support. Tried reaching out to the developers directly and no reply. Very frustrating.

The module is not reporting any vqmod nor error log error but it's not working properly. Once ESPONI_CFO_v2.78.xml is enabled, it changes any product amount in the cart to zero (0). Formulas are not working either.

Any help or suggestions would be great.

Thanks.
