Sorry for the late reply, yeah I tried re-downloading it a few times on both laptops.Rly confused why it doesn't work, since it indeed was working before the 2nd chapter u_u
Oh, that's a easy one. You need to download the RPGVXAce Runtime.
Here's the Link: https://www.rpgmakerweb.com/download/additional/run-time-packages select "RPG MAKER VX ACE" then click download now.
then just extract the archive you just downloaded and execute the installer.
If something isn't working, just reply, I like to help People (・ω・)
