I wrote about 0.3.4-5 and 0.3.4-2 in my previous post, because there were important changes of the booting code then.
*All* previous versions since 2005 are available to download.
Change logs are available too, through the "News" page in the main Gparted CD.

However, very old versions are perhaps lacking drivers. Furthermore, don't use 0.2.x versions, because they are too old and buggy. If 0.3.1 version works, you can try it. Details on your hardware (motherboard/chipest/BIOS versions, hard drives + optical drives) would be useful too.
