Protection PRO and Internet security

I have purchase numbers for both products but am constantly chased by AVG to update them and don't know how to check that I have them. I have tried downloading them again just in case it didn't work first time but the website won't let me do it saying there is an 'unexpected error'. I just feel I am being conned but don't really understand what on earth is going on.

Hello Chris,
We apologize for the inconvenience caused.
We understand that you are experiencing issue with installing AVG Product.
May I know the exact error message you have received?
Are you experiencing this on installing both your AVG Internet Security and AVG Protection?
Thank you.
