Is what's in the title the exact wording of the second error?
In any event - most likely a write permissions issue at the OS level, with the destination folder. Fix that and you should be OK...
ok how can i fix that please?
Fixing permission issues is something that has to be done in your operating system and its a a bit different for Windows or Mac. e.g Do a google search "Setting permissions in WIN 7/ Mac OSX 10.10".
