And with all of that they don't tell you it's a trial version. Yup...got that annoying pop up that says you have this much time left before it becomes non-functional. I got rid of it.
Sorry, only noticed this now because RedneckDude pointed to this old thread in 'Meter themes/icons in Nexus Ultimate'. The WC forums REALLY could do with a 'watch this thread' setting. Anyway...
Are people so used to unresponsive tech support departments that they don't even bother trying to contact them before taking action?
The GOTD version required you to get a serial number on the day of the promotion (this was clearly stated on the README file, but don't feel bad, you weren't the only one who chose to ignore it). Without the serial number, the GOTD version of Nexus Ultimate would run as a trial, as you have discovered. There are plenty of good reasons to do things this way, which I won't get into detail here because they have to do with copy protection of the software (Nexus Ultimate is NOT free, but commercial software, after all).
Another enforcement of the GOTD promotion (and this applies to every software they promote on their web site) is that it can only be installed on the day of the promotion. If you need to re-install at a later date, you will have to purchase the full version of the software. This is where Winstep delievered above and beyond most other software listed at GOTD, in that it allowed you to upgrade to Winstep Xtreme for only $14.95 or to the regular version of Nexus Ultimate (which you can re-install whenever you want and offers you 1 full year of free upgrades) for only $12.50. But for this you need to have the GOTD version of Nexus Ultimate installed, registered, and running.
Every user who contacted Winstep support with the same problem as you, or formated their PCs and wanted to re-install Nexus Ultimate, were offered the above deal. Most jumped at it, as they realized that a) it was their own mistake not having read the README and it is a GREAT deal, considering Nexus Ultimate costs $24.95 and Winstep Xtreme $39.90. Interesting fact is that, from the small minority that didn't, some got as far as insulting me personaly, even though they had nobody else to blame but themselves for not following the instructions.
