Hi

Sorry if this double posts...the other did not list.

Is there support for mac 10.7.5

When i d/l the version thats available nothing happens when i launch the dmg. I get the device but no further action happens..i cant install the client. i have an access from work which was supplied for me and now i cant get the client to run.

many thanks
