wireless help

[lloydusa]

I have a peachtree 2003 complete acct. I'm was working on a wireless network, everything was ok, but the problem started a month ago when i received a message error I/o, and many other messages about lock tables(userprefs.dat. status.dat), according to peachtree support team it's a network issue...i reinstall a fresh version on all my pc's i tried everything

Can someone help me out with this matter
Thank You

I suggest to repair or restore your data!

But under my wireless network it's not working(was working fine for about 2 years), and when i upgrade my network to a wireless G (linksys router with speedbooster, linksys wireless adapter G), it seems that they shut down some ports, or probably it's i microsoft update issue...i spoke to everyone that i could but no one had an answer(peachtree, microsoft, linksys)
I went back to a wired network.....
Any suggestion?????????????????
