Hey lads. Since .25 was released, my launcher has been acting weird; the news section is completely empty and the update button is greyed out and cannot be clicked on. I can still play–the play button is fine–, but I cannot update to .25. I had this exact same issue on my other PC as well. Any suggestions? -King Potato p.s. No bloody way I'm going to use the patcher again, it's given me some issues with .25 p.p.s. Please see if you can come up with suggestions that don't involve reinstalling. That's a b!/ch to do...

To all of those who said that the unit used for liquid fuel is undefined, I just presumed it was in litres because the liquid fuel tanks section on http://wiki.kerbalspaceprogram.com/wiki/Parts gives you the fuel and oxidiser capacity in (L). With that information, I just put the amount of fuel I had at the time into the formula ÃÂ=m/V and turned it into m=ÃÂV. In case the wiki is actually wrong, this should solve my problem, but I'm still not sure... This is actually the same formula used here: http://wiki.kerbalspaceprogram.com/wiki/Cheat_Sheet Because I intended the whole calculation I was doing, to be created by myself, I didn't want to use anything similar to that, seeing as how I haven't had logarithms in school yet

Hello, fellow kerbonauts! I was playing kerbal space program the other day (surprising, huh?) where I sent an unmanned probe to the Mün. When I landed there, I noticed that not much fuel was left. In order to know whether I would be able to get it safely back to Kerbin, I needed to know how much delta velocity the ship had. As I like finding out how to calculate things myself, rather than just trying out or using an existing formula, I started doing some research on how I should calculate everything required to find out delta velocity. This included properties of a variety of rocket parts, and what specific impulse is. Everything went well, until the formula I made for calculating how long I could burn with the amount of fuel gave an invalid, unrealisic answer. I could not figure out where the issue was, and started doing some tests on the launchpad, while observing different factors I used in the formulae. One of these, was the different mass of the spaceship relative to the amount of fuel inside. For the calculation of fuel mass, I used the information the KSP wiki gave me, including the density of liquid fuel and oxidiser (both of which appeared to be ÃÂ=5 kg*L^-1). However, the fuel mass I found did not match those of the tests I performed. I googled some more, and other than the wiki, the actual density was nowhere to be found on the web. So here's my question: Am I just overseeing something, and just being an idiot? Or is the density stated on the wiki actually wrong? If so, can someone give me the correct density or a different way to find the wet mass and dry mass of a fuel tank (other than using addons e.g. mechjeb)? Thanks in advance for your answers. P.S. If any information required to answer this question is lacking or insufficient, please just say so in the comments. P.S.S. I did not use any mods.
