SharePoint 2010 functioning incorrectly after installing Search Server Express

Hi,

and thanks for taking the time to lend a hand and your knowledge. I have a Sharepoint Foundation 2010 site that has went crazy after I tried to install Search Server Express - which FAILED near the end.

I have checked the logs for the correlation Id provided on the SPF site when it errors.

03/05/2015 10:02:23.75  w3wp.exe (0x101C)      0x1264 SharePoint Foundation          Runtime                       tkau Unexpected System.NullReferenceException: Object reference not set to an instance of an object.    at Microsoft.SharePoint.ApplicationPages.ListEditPage.SetSectionLinks()     at Microsoft.SharePoint.ApplicationPages.ListEditPage.OnLoad(EventArgs e)     at ASP._layouts_listedit_aspx.OnLoad(EventArgs e)     at System.Web.UI.Control.LoadRecursive()     at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) b5f617dc-5d0e-4c5b-92fa-1b7e5a12f2e3

My issue now is that it appears I will need to remove the SSE install, but from what I can see online this can have a serious impact on the SPF site. I really want a few opinions as to what my best route to take would be on this issue.

Also, I am wondering what would happen if I run the install again of SSE, would it resolve,

OR

is it going to be a matter of detaching the content database and reinstalling SPF2010, and reattaching the content database (P.s. I have a back up of this database of approx. 4Gb from before I ran the install that has ruined the last two days of my life!!!)

Kind Regards,
