I've been tuning the software for years, unfortunately each time the poker sites put out new updates, there is a possibility it breaks things. This new iPoker update has caused problems. 
However I just tested it again on my machine and it worked ok. Are you sure you Removed and re-Included the "iPokerNew" site?
One other thing you can try, I'm not sure if the error message suggests it or not, is to create a File->New Layout, with a slightly different grid slot size. Then try Including iPokerNew into this new layout, and see if that fixes it and you stop getting the error. That may solve it for you.
As far as Party tables not detecting, yes they too put out a recent update. This alpha version should detect those new tables now. If you find any that aren't being detected, please use the SaT menu item for Help-> Diagnostic-> Get Window Title, and paste me the results
