My freenet wont connect or announce after a bit

So I installed freenet after not using it for about 4 months
and everything was working great then I lost all my connections and
couldn't find a way to get them back I use open net the ports are
forwarded and it all should be good but it didn't want to connect. so i
copy pasted all my important things like bookmarks and freetalk ids then
reinstalled freenet it was working and i got everything working again
but after about 4hours it all broke and i cant fix it I don't want to
reinstall every 4hours because that's a bitch.

    Freenet 0.7.5 Build #1372 testing-build-1373-pre7
    Freenet-ext Build #26 (29 is recommended) r23771

checking into wrapper.log I found this
INFO   | jvm 1    | 2011/05/10 18:50:37 | Caught in PacketSender:

i used to get the ip cant be found message but i starting using the
static option that removes the message but wont make it connect

also this is almost always showing
Freenet is connecting to the network - this may take a few minutes.
Performance will continue to improve during the next few hours. This
will happen each time you shut down Freenet for more than a few minutes,
so try to leave it running 24 hours a day if possible. We have recently
sent 0 announcements, 0 of which are still running, and added 0 nodes (0
nodes have rejected us). We are currently connected to 0 seednodes and
trying to connect to another 15

thanks bober

PS how can i use GPG keys on a mailing list
