okay, but I can't browse for the .txt file of my previous level because every time I finish a run, I always delete my old saves and I was recently told that I can get an aura if I send a replay of my game. But I didn't thought I need a replay + text file + screenshot. Though yeah I can always see a reminder that I should take a screenshot of my previous game but some told me that that screenshot is unnecessary. Later, someone introduced me to this site and now I just learned these kinds of stuff and thought replay file would be sufficient. Anyway, this good person's in game name was lwlnerl or something resembles that ign and he told me that I need to save replays and I did eventually.
If your username is the same as your battle.net ID then you might be able to get a majority of your replays from the ENT stat page here. That of course depends on if you used their bots for playing.
Do note that dependent on your current patch, you may need to downgrade your installation to 1.27b for verification purposes. Older replays do not work with patch 1.28. If you need more info on how to downgrade I made a list for scurged on his thread here.
