It's most probably a ownership problem. Your original folders are set with a owner that is different than you.
Right click the problem folders and sellect Properties.
Sellect the Security tab.
You'll see who have what autorisation for that folder.
ADD yourself in the top section.
Click the Advance parameters button. Sellect the Owner tab.
Sellect your identity.
Click the box "Replace owner of sub-containers and objects".
Click OK. Click OK.
You should now have ownership of your former folders and files.
