Good afternoon!
Here is your answer:
You need to download BAM if you don't already have it.
"The solution, is to be sure you are using BAM to play the table, and then copy a physics xml file (from the BAM / XML folder) to where the table is, and name it the same as the table file. Most likely the fp-p2.6 or fp-p2.7 xml will be needed for SLAM's older tables." Quoted from Terry Red from this, "Weak flippers in SLAMT1LT tables" forum post.
Any other questions, feel free to ask.
Have a great day!
