FsRealWx 2040622 crashes decoding metars

I am becoming increasingly frustrated now with this bug that was happening rarely but seems to happen more often now!

I set FS2004 to the location I will start at, then open FSRealWx and it downloads the data, decodes the metars and when it gets to the second to last metar to decode, it pauses and says it must close. For example, loading up at KMIA, FsRealWx to decode 180 metars, gets to 179 (X61) and suddenly pauses and says it must close due to an error! It also happens mid flight sometimes too, what the hell is going on?!
