I'm running SharePoint 2007 and got a Server Unavailable message after installing this web part. Any ideas why it have occured? I already followed the Microsoft suggested steps on fixing the issue but its still not working.

Allways try on a Sharepoint VPC before a real situation.

This webpart register on gac "UploadWebPart.dll", 
add to your WebConfig, <SafeControl Assembly="UploadWebPart, Version=, Culture=neutral, PublicKeyToken=71a3a1eef4afa0f1" Namespace="UploadWebPart" TypeName="*" Safe="True" />
and add files to "C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\FEATURES\UploadWebpart"

Verify you Event Viewer, to see what errors came.
Verify if is another error.
Try a IIS reset, 
Verify if your Application pool/Site on IIS is down.

To remove, go to your sharepoint Central administration and select  "Central Administration > Operations > Solution Management > " and select "uploadwebpart.wsp " then "Retract Solution".
