Hello Markus,
first few things to verify
1) are you behind a proxy in your work environment? If yes, does it require credentials?
2) from the log I can see you are using Pins tool version 2. Currently supported version is already v4. Is there a specific reason why you stick with older version?
3) "Version 1 files are not supported" I can see just warning message that if you save it with newer tool, it might not work in older tool (tools should be backward compatible, not forward compatible)

Back to the proxy, if you have http proxy which does not require name and password, you can specify it in this file
c:\nxp\i.MX_Pins_v2\bin\tools.ini
fragment of tools.ini (probably the java.net.useSystemProxies should be set to false)
-Djava.net.useSystemProxies=true
-Dhttp.proxyHost=somecompany.proxy.net
-Dhttp.proxyPort=80
More details about specifying the proxy can be found on Oracle web site: Networking Properties
And as a last resort if you provide the board/processor you would like to use I can prepare offline ZIP archive which you can download and manually extract into proper directory.
Regards,
Libor
