[Plugin: Custom Content Type Manager] 0.8.6 won't activate due to fatal error

I was just trying out your plugin (version 0.8.2) when I saw it had an update to 0.8.6. So I updated it automatically and it won’t activate due to a fatal error.

Fatal error: Undefined class constant ‘txtdomain’ in C:\Data\xampplite\htdocs\testsite\wp-content\plugins\custom-content-type-manager\tests\CCTMtests.php on line 110
