Okay, So I used to have Unity about 6 months, I recently downloaded the newest one (3.3) & when I clicked run Unity, A Register box showed up, Internet Register didn’t work (ilinet.dll won’t work)… When I click on manual, it gives me two options that is top of the ‘Next’ button (When I clicked on Next, it told me ‘Thank You!’ But won’t let me click finish); Save License Request & Read License. I Save the license on my document files & when I finished, I clicked on Read License, I couldn’t find it but than noticed Save & Read were two different files… One was *.ilr & the other was &.ilf . I Tried Manual but i don’t know how to do or what file I should be looking for. Please Help! Ive been struggling with this problem all day! Ive tried reinstalling Unity 3.3, & tried restarting my computer, nothing worked!
I know that many people have had problems with activation before.
