Unless you also did something else after upgrading Admin Tools Pro, the cause and effect you mention seems completely unrelated.
Let's take one thing at a time. Admin Tools does not modify in any way the Joomla! extensions installer. As a result, not being able to uninstall sh404SEF is unrelated to Admin Tools. I'd look for permissions issues in the filesystem.
As far as JCrawler is concerned, "quit working" is a little too vague. I am not sitting in front of your computer, I don't know the URL of your site and I don't have access to your security exceptions log. If you see an entry in the security exceptions log, what is the reason mentioned? If there is no entry in the security exception log, please try the
.htaccess maker's troubleshooting instructions (if you're using the .htaccess maker). If this doesn't help or had not previously used the .htaccess maker, the problem is unrelated to Admin Tools.
Please help me help you. If you just tell me that something doesn't work, I have no idea where to start. Guessing is not my strong point :)
