    An error occurred when attempting to change modules


      OSX Version 10.9.4.  Bought Creative Cloud yesterday as a monthly subscription and downloaded Photoshop, Lightroom and Bridge.  Lightroom shows a grey screen and has never worked.  Select any option e.g. Library, Develop, Map and get "An error occurred when attempting to change modules".  Went to help and re-installed.  Now needs a serial number.  One not sent with emails.  Tried to use the 30-day trial version but still gives the error notice.  Have deleted the com.adobe.Lightroom5.plist as one solution suggested.
