I downloaded the explosive+ mod for 1.5.2 and I opened the old launcher up and it said forge had a fatel error and I don't know what to do. please help me here.
...WHY did you download it from skydaz.com instead of something a lot more legitimate looking like, say, the Forge post on the forum's old versions section?
And this time it hasn't worked, so try the forum post instead. If something doesn't work, it is usually a better option to try a new way than to complain.
