Hi guys, I'm not new to Kerbal but I'm new to the forum. I was running 24.0.549 with no issues at all, the only mod was Mechjeb. I finally got around to upgrading to 25, and now I'm experiencing a lot of problems. I'd like to think it's due to my hardware, but I exceed all minimum requirements. Incidentally, I've wiped Mechjeb, the game itself is "clean" hence it being posted here! So... specs... Processor:- Core2Duo E8400 3Ghz Dual Core Ram:- 4Gb Hard drive:- 1Tb (700Gb free) Vid card:- NVidia GeForce GTX550 Ti 1Gb Monitor (this will be explained):- Xerox digital one with DVI input So. I used to have 24.0.549 set to 1280x1024 as this was the "recommended" Windows res. 1 - First issue with 25, it doesn't get past the loading screen. It just crashes before giving the option to load a game. I used the launcher to change this to 1024x768, and it launched. 2 - When going to build a rocket, on entering the building the screen flashes briefly and then loses all of the outer icons... all of the new/save/launch etc, and even the parts menus. However, the options still come up if you mouse over them. 3 - When building the second part of the rocket (so command pod's there, try adding something else), the game crashes out again. I've tried a reinstall, same result. The other building are fine, I can use the admin building, accept missions, buy science tech etc, it's just getting past the building a rocket part. Apologies if this has been mentioned in another thread, but searching "crashing" brings up more results than I can read! Would really appreciate any advice as at the moment I can't play as I can't "downgrade" back to version 24 again!
