Can't purchase HALion 3 to 4 Upgrade

Dear Sir
Good Day

I live in Jordan-Middle east and there is no distributer in my country, The destributer for my Region is located at UAE which is about 3 hours by airplane.
I’m trying for the last 2 weeks to buy a downloadable update for my Halion 3 and there is no link at your homepage for this update, it looks that your page is different from country to another as there is no link for this purchase.
Please help as there is also no support E. mail also
