I found the problem in the new node code where stake weight and network weight do not rise.  I am reverting these changes and will make another announcement when thats complete and tested.  Until that is done please use the older version of the wallet which is on audiocoin.eu
update i was just notified that the mac wallet is also effected.  We have pulled this version from the website and will replace it when the new build is done.
We apologize about any inconvenience this has caused and I can assure you that no coin weight has been lost.  If you do have the old version of the mac wallet you can easily revert by simply opening and running it.
