I cannot find its source code (though licensed GPLv2), cannot enter username & password unless I run it with elevated permissions, and cannot even send feedback due to ASP.NET configuration issue "Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster."
I have sent feedback to the site host (dotnetpark.com) regarding this misconfiguration, but I have not received any answer and it is still incorrectly configured after a week.
The software updated from v1.0 to v1.1 this morning, and the problems still exist.
