Crashes on opening

I have downloaded LibreOffice 5.0.1.2 english and have tried to open it on a Mac sys. 10.10.5 english. It crashes on opening and will do so for 3 or 4 tries. It will finally open and seems to be okay. I do not think it should crash on opening. I have not used it for great lengths of time but the short amount of time I’ve used it it seems to be okay. The crashing makes me kind of nervous about using it. Does anyone else have this problem and is there a solution?
