Support form problem

I do not see the theme I purchased 2-3 yrs ago in my download.
I tried to submit form but it keeps saying invalid URL format. The format is correct. Tried to submit several times but no luck.

Hi,

Can you tell me exact your purchase theme name ?
check that theme documentation to contacting that item author if you have it.
Or
You can get in touch with expert web programmer from Envato Studio.
They can help you out from your issue.

Thanks!

Author only refers me to Envato. I need support them but their support form not working

Your purchase item support is expired as your word you say you have purchased item 2-3 years before.
You have to increase support or can getting new license or have to getting touch with expert developer.
