I was told that there was an internal error after I inserted the free serial or existing commercial serial when the demo expired in my Win10 !(https://d2r1vs3d9006ap.cloudfront.net/s3_images/1441247/RackMultipart20160629-69751-1uferep-3_P472M KI2_MJCCA_ DW_inline.png?1467201113)
Please advice any solution, thanks for help!
are you sure you are copying the license key correctly?
I see 2 PRO licenses and 1 FREE under your email address. The FREE one isn’t activated. Is it the one you’re trying to use?
Please contact me at firstname.lastname@example.org with a link to this forum topic if trying to copy the key again does not work.
