Yeah, keeping the tables up to date is a pain.... Especially when you have a large download just for some slight changes to the files.
Anyway, there was a version that had a timeout years ago. The latest removed this, but there have been some script changes since (but I didn't think much).
try and set your clock back to the release date of the version you have (I'm assuming you can fidn that date in one of the files or readmes)... I think it will start working.
Next, you could look and try to find the very next version.... and not upgrade to the apsolute latest. that might make the fix easy, but you would be missing out on the new tables.
last... upgrade them... But do it one by one. Giving you a chance to see each table again. But this assumes you can upgrade you cabinet pretty easy. But get the latest code... remove all the tables... download one and play.... and dont upgrade more then a few at a time. Great way to have new games. (think Raz's release cycle...sure some complained, but if he hadn't, nobody would have played some of those old cps2 games)
