When adding forge-1.7.10-10.13.4.1558-1.7.10-universal I get the error mentioned above in the Thread Title. From what I have found it means there is another Forge version installed, theres not. The server is based on the modpack FTB Lite 3 and im playing on it with friends and adding some mods as we go. I have to add this mod specific for Journey map or I might be doing something wrong(been a while). Sadly it doesnt create a crash-log but I was able to copy the CMD window you can find the window here: http://pastebin.com/0SQCAWMu What am i doing wrong? Let me rephrase the above, hwo do i udate from Forge 1448 to 1558 withouth the freaking server breaking.
