中学党四个月零花钱了 求解 急死了

翻了一下Cloudy Nights和开源天文论坛，没有发现这样的错误，目前认为可能是使用人数限制或者码错了。请问楼主是几个人合购的？

查看邮箱，以最近的邮件的激活码为准

以前是否用过试用许可证？据说需要先删除。PI FAQ 2.22
That happens because you still have the license file corresponding to your previous (and expired) trial license on your machine. You have to remove that file manually before activating your new trial license. The license file is a small plain text file named PixInsightLicense on the following folders:

On Linux and FreeBSD:
$HOME/.PixInsight

On macOS:
$HOME/Library/PixInsight

On Windows:
%UserProfile%\AppData\Roaming\Pleiades

where $HOME or %UserProfile% represent your home folder, that is, your personal folder where you usually have your documents, images, music, etc., on each operating system.

Once you have removed your expired trial license file, you can run the PixInsight core application to activate your new trial license with the new activation codes you have received.

然后是“无效的许可证” PI FAQ2.23
Your license file has been damaged or corrupted for some reason. This may also happen if you are using a trial license and something has tampered with the encrypted data transferred between our server and your computer.

To solve this problem, first you have to remove your damaged license file, which is a small plain text file named PixInsightLicense on the following folders:

On Linux and FreeBSD:
$HOME/.PixInsight

On macOS:
$HOME/Library/PixInsight

On Windows:
%UserProfile%\AppData\Roaming\Pleiades

where $HOME or %UserProfile% represent your home folder, that is, your personal folder where you usually have your documents, images, music, etc., on each operating system.

Once you have removed your damaged license file, run the PixInsight core application to reactivate your license. See FAQ 2.10 for complete information.

解决了！在群友帮助下 把appdata里的许可文件拷贝了
