'Cannot find the resource string number 25202 in resource 626393088

Cannot find the resource string number 3898 in resource AeccUiLand80.
Cannot find the resource string number 25202 in resource 626393088

It seems the issue you have may be related to user profile only. To test it, see if you can login as different user to the same machine and see if you still get an error. If don't then please try following procedure: http://usa.autodesk.com/adsk/servlet/ps/dl/item?siteID=123112&id=14929107&linkID=9240697
