Hello userCold9,
Thank you for your post.
Can you check the physical location of ColdFusion installation and confirm that CFIDE folder is available inside the cf-root and index.cfm/enter.cfm are residing within the same. For login issues, i would suggest the following:-
Try a different browser or a different system
Use the system's ip instead of localhost
If still you are facing difficulties, then please repost with your environment details.
Regards,
Anit Kumar
