I had this problem when I was updating MegaDroid to version 1.35. I even asked support about that. But then I was really happy because that was just my mistake during update.
To update, I recommend you to use manual installation instead of automatic installer. You need two files: MegaDroid.ex4 and MegaDroid.dll. Follow these steps:
1) Close MetaTrader, where you’re going to install MegaDroid to.
2) Open “/Metatrader folder/experts/” and replace old MegaDroid.ex4 there with new file.
3) Open “/Metatrader folder/experts/libraries/” and replace old MegaDroid.dll with new file.
4) Run MetaTrader and reattach robot to the chart to update it’s settings. Enter your Receipt code and leave it working and making money for you!
MT4 Crashes happen when you forget to update dll file. Sometimes installer could not update this file, because of Windows Security. You should do that yourself during manual installation.
