Muse Hub Error on Sending verification Code, can't receive it

Hello,
It's been four days since I asked MuseHub support to correct their emails sending the verification code. In fact, my supplier refuses them because they are incorrect and malformed. I bought soundFonts for over 100€ and I can no longer use them. Please do what is necessary with MuseHub support which does not offer me a solution to log into my account.
Error reported by my internet provider "free.fr":
The SPF entry for this domain is incorrect:
musehub.com descriptive text "v=spf1 include:spf.protection.outlook.com -all"
musehub.com descriptive text "v=spf1 include:_spf.google.com ~all"
It is not allowed by the standard to put multiple entries.

Thank's for your help
Robert
