I am having problem starting Civil 3D 2012.....When i fisrt installed it, i entered the serial and cdkey, and all went well, i had the green check mark at the right of each (see first image) . But when i want to start the software for the first time, it ask me again for the serial and cdkey....but this time, the CDKEY doesnt seems to match !? (see second image)
but the serial and cdkey are good, i can install the software on an other workstation !?
