Sliders crashed my site...

I was running the trial version of sliders. It was working fine.

I purchased the pro version and I could no longer see the slider on my home page. I figured, I had to uninstall the trial and when trying to uninstall the sliders, it crashed my site?

I get this error now when going to my site; http://shippersmall270.com.mytempweb.com

Server Error in '/' Application.
Object reference not set to an instance of an object.
Description: An unhandled exception occurred during the execution of the current web
request. Please review the stack trace for more information about the error and where it
originated in the code.
Exception Details: System.NullReferenceException: Object reference not set to an
instance of an object.
Source Error:
The source code that generated this unhandled exception can only be shown
when compiled in debug mode. To enable this, please follow one of the below
steps, then request the URL:
1. Add a "Debug=true" directive at the top of the file that generated the
error. Example:
<%@ Page Language="C#" Debug="true" %>
or:
2) Add the following section to the configuration file of your application:
<configuration>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>
Note that this second technique will cause all files within a given
application to be compiled in debug mode. The first technique will cause only
that particular file to be compiled in debug mode.
Important: Running applications in debug mode does incur a memory/performance
overhead. You should make sure that an application has debugging disabled
before deploying into production scenario.

I deleted both of the slider files and now my site is back, but.... Before I re-upload the slider thingy again to try again. I hope somebody can tell me if my purchased version is different from the trial version? I didnt get a link to download when I purchased. It said "n/a".?
