Cannot Access Sharepoint Central Administrator

After some Microsoft updates a few weeks ago, I can no longer access my
SharePoint Central Administrator. Below is the error I get:

Server Error in '/' Application.
________________________________________
Runtime Error
Description: An application error occurred on the server. The current custom
error settings for this application prevent the details of the application
error from being viewed.

Details: To enable the details of this specific error message to be viewable
on the local server machine, please create a <customErrors> tag within a
"web.config" configuration file located in the root directory of the current
web application. This <customErrors> tag should then have its "mode"
attribute set to "RemoteOnly". To enable the details to be viewable on remote
machines, please set "mode" to "Off".

<!-- Web.Config Configuration File -->

<configuration>
<system.web>
<customErrors mode="RemoteOnly"/>
</system.web>
</configuration>

Notes: The current error page you are seeing can be replaced by a custom
error page by modifying the "defaultRedirect" attribute of the application's
<customErrors> configuration tag to point to a custom error page URL.

<!-- Web.Config Configuration File -->

<configuration>
<system.web>
<customErrors mode="On" defaultRedirect="mycustompage.htm"/>
</system.web>
</configuration>

I also checked my event logs and I get some reoccurring errors:
