Installing Catia Student Edition in another computer

I recently bought a new computer and tried to install CATIA Student Edition. After the installation Target ID reported a new PC ID. I tried to download a new license but I did not get. I believe that the license is valid for one computer. Then I tried to import my old license which seems to be locked to my old computer ID. The Target ID reported that it failed to update a registry key which I changed manually in the end. It reported two different computer IDs with two different keys. After a couple of days I tried to run CATIA and the license problem comes up again and none of the keys work. I have requested again a new license but I never received it. Obviously CATIA Student Edition has a one computer license policy, which is only logical. But how am i supposed to install and run the program to my new pc though? I will gladly delete the old computer ID so i can use this one because most likely the system believes that I am trying to install it in two different computers but there is no way for me to delete it through the site.
