SERVER ERROR - When purchasing Theme

[CY]

I am trying to purchase the Taiga theme after spending almost a month customising it. Every time I click buy it gives me a server error. I tried a new card, clearing my cache, checking my bank, waiting a couple of days... I check my billing and apparently it has been refunded to me, but no funds come out in the first place. Nothing is working. Just keep getting a very vague server error. 

I can't make my store live without it so any help would be much appreciated
