I have activated the code but when the window closed. now I can not re- enter the code to download . how do I download it now?

Hi, can you help me? I'm student at Deltion College in the Netherlands in Zwolle. This morning I tried to activate my instalation code. I activate my code but I was shocked by the fact that I had to provide my bank details and have closed the window. Now I try to re- activate my code glands adobe cloud ( illustrator, photoshop) to install on my laptop but it will not work because the code has already been used once .
