The original poster ignored recommended settings, ignored warnings displayed by AmiBroker, used registry hack to disable 500k bar limit and entered 20x more than recommended "number of bars" for 1-minute IQFeed database (2 million bars instead recommended 100k)
If you load 40 tonnes onto Ferrari it won't go. And that's no surprise. Always, I mean ALWAYS use recommended settings (as presented in tutorials and videos) and it will work perfectly. As with any machine, any equipment, etc, if you load 20x more than manufacturer recommends you can expect it to run at least 20x slower or not run at all.
