Temporary fix- after Windows starts, go to Run and type msconfig then hit the ENTER key.. On the StartUp tab, uncheck Wild Tangent, it's causing an error then probably because the removal didn't completely do it. Also go to Start>Control Panel>Add Remove Programs. If Wild Tangent is listed there, try and remove it. It is a known spyware. Wild Tangent usually tags along with Weather Bug and AIM. Weather Bug is another pain. If the above does not work, unregister the cdaEngine0400.dll. To do that: Click Start>Run>type the following: regsvr32 /u cdaEngine0400.dll Hit Enter. Now, go to C:\ProgramFiles\WildTangent\Apps\CDA\cdaEngine0400.dll in Windows Explorer and delete that dll file. indicarol <indicarol@xxxxxxxxx> wrote: Could someone please explain to me what this is and what I need to do?
