I understand why their software works on some systems while it doesn't on others... Nothing wrong with my system... they are just literally sh*tty programmers... beginner amateurs at best... self taught... that's why I think they rest of the software is also very dodgy.

What do you think

Do dollar cost averaging.
Monero's long term trend is up, but its price is extremely volatile.  That's why I suggest dollar cost averaging.
Let's say that you have x amount of cash that you want to invest in monero.  If you spend all that cash right now on monero, the price could drop by half, and you wouldn't feel very good about that.
So pick a timeline over which you want to make your investment and do it gradually.  You could buy a certain dollar amount of monero every week for the next six months, for example.  Or, instead of caculating it based on dollars, buy a certain amount of monero as priced in bitcoin at a weekly (or whatever) interval on poloniex or bittrex, or your exchange of choice.
