Ive got an issue registering, Im using a home license activation code. Got a new serial number, (for home license) , request code, used those to get an activation code........success!. I got that, open inventor, say Activate product.......put in my home license serial number, type in my activation code (i cant paste it, it wont let me) hit next, and no dice. Ive looked at the code 18 times, only thing im not sure of is if the "0"s are the letter O or the number zero. So anyway ive been calling 1-800-538-6401 (Autodesk Support) and getting no answer no matter what option i choose.
