mk2 megane chip tuning box?

Eyup Guys, I bought a ProBits plug in chip tuning box for my mk2 03 reg megane 1.5 dci estate it`s been on for 3 yrs and I was delighted with the difference it made, I have now scrapped the car and I have bought a mk3 2010 megane 1.5 dci estate, I messaged ProBits who I believe have been bought out and asked if it was compatable with the mk3 they didn`t answer my question just sent me a link to what looks like the same chip as I bought 3 yrs previous so I asked the question again and there reply was technology has moved on since I bought the chip so it would not be compatable, I felt as if they were just trying to take my money, what`s the general feeling on this please. Regards George.
