That you "somehow upgraded to 2009" may be the problem. There is a special way to do this in stages, otherwise some upgrades wouldn't take and you had a borked system. Search the forum for this thread. Are you fully upgraded according to Synaptic? If you need to reinstall you should download the 2009.2 .iso, burn it to a CD and reinstall. Just don't let it format your /home partition. Then, you will still have to upgrade, as many packages are out of date from that release. In a few weeks 2010 .iso will be released. I understand that will also need a fresh install because so many basic system packages are new. I suggest you regularly read the forums to keep up with what's going on with PCLOS. That way you avoid problems.
