okay so... I've always used version 2.1.4a for my TASes and everything always worked fine. But earlier ago when I ran the .exe, some strange error happened but I thought it was just something silly, so I closed the window and didn't even read. Then the .exe completely vanished from my computer, and now when I want to download the emulator again, this happens:

basically, EVERY SINGLE VERSION of the emulator works here, except for 2.1.4a. And it's EXACTLY the version that contains all of my TASes. I want to encode my TASes again, so unless if the movies from 2.1.4a are compatible with another version of the emulator, I'll never be able to replay my movies again, ever.
Seriously, I'm dreadfully desperate here. I put a lot of effort on my TASes and I don't want to redo all of them from square one. I want to make them work again. Please someone help me!
