I also use the PT4 trial atm. It says that it stops importing hands after 30 minutes, but that is not true. It imports all hands, tracks your winnings(and losses) and even offers you a free hud for 30 days.
I have set it under HUD->edit profile to only show VPIP and PFR, hands played, auto notes and name (you might actually get rid of name and PFR). The 3bet range and other stats do not make sense if you dont have hand history over thousands of hands , and this "HUD light" gives you all important information. I really like the automatic note function: "3-bet with range {55, J3o} ", barrel river with air" tells you everything you need to know;-)
I also used some color coding in VPIP (clicking on VPIP and edit the color range), e.g. with VPIP < 10 in red and >40 in green, and whenever I have 100 hands+ I mark the player in the poker lobby with the accordiing colors (for the time the trial runs out, but also to get rid of unprofitable tables before even posting the 1st blind). To make it even less confusing, I changed the opacity under HUD options, chose not to display player avatars in the poker lobby, and moved the HUD to the free space. With this I multitable 9-16 tables without trouble, it helps a lot to get rid of tables which do not bring any money, and prevents me from really costly decisions (e.g. when you have the note that someone 4-bets with 44, you wont give up your QQ)
by the way, with a BR of only 5 Buy-ins you will have a good chance of going bankrupt, no matter how good you play. Actually, your chance of busting correlates with your bb/100, so you want to maximise your winnings, not your winrate. Don't multitable if you are so strongly underrolled.
