To be honest the problems started after beta1 was released, before it had been properly tested people started asking Matt for other features to be added. I tested all four versions and can say that beta 1 was the most stable of them all, but it still had problems, beta's 2 to 4 should be sent to the trashcan as thier that bad.
As far as I'm concerned the cache feature is the biggest problem, during beta testing I lost 4.5 gig from a 20 gig HDD, I couldn't find the problem until I looked in my FL directory. Every mod's custom content from systems to CMPs, were in there, now none of these mods were built for the cache feature so nothing should have been left, but to then add insult to injury, the next time I activated one of those mods FLMM made a backup of the custom content instead of reusing it.
If you use 1.4 with some of the larger mods you will find that you will be deleteing your FL directory and reinstalling it on a regular basis.
Now if a mod is built properly to work with 1.4 you won't have any problems, but in reality you need 1.31 & 1.4 installed to use most of the mods we have.
If you still want to use the "freshstart" then check the FLMM forum section here on TLR, all of the information is available there as it was Argh's idea to start with (you'll have to go back nearly 18 months to find it though). If all you want it for is the OpenSP then check
this out, it's basically Chips's opensplite with one major difference, the content.dll has been remove and replaced with a slightly modified newplayer.fl.
