What do you see in AMS maintenance Tool, Licence. Do you see proper license count with proper expiration date?

When you can draw a conclusion, that licence file is corrupted or incorrect, you have knock your reseller’s door for new license file. Otherwise ask for money back guarantee (and then buy license on-line with support :-). But at first, try ask your reseller. Nobody can exclude, that license file was damaged during download (if you receive it via email)
