Working with Mmass?Mass spectrometry?Evaluation?

Hello,

I have several questions about this program. I have been given spectra to evaluate, which I am supposed to analyze using Mmass. Unfortunately, the program crashes frequently, which is a clear indication that the adduct is incorrect. But in the spectra it is usually the case that only H+ peaks are visible next to the base peak, but no further away peaks for potassium, lithium, sodium or ammonium. Does anyone have any suggestions for a solution to this problem, or can potassium etc. still be present as an adduct even though the peaks are not this far apart? After trying several times, I still cannot get the structural formula that is on my list. I have now solved the problems using the mass and a list of what could be in it. But to be on the safe side, I would like to know how and possibly with which other program I can solve these problems.
