Well I apperently can't play any new modpacks I try to download because of this, if I already had them downloaded they will play but anything new and this happens. I have tried forcibly updating and making sure Java is up to date, not sure what else I could do. I checked the log and this was there error I was getting (If this is the same as the log it was telling me to check, I couldn't open the .lck one) and I do have an internet connection btw... kinda odd to give that as an error possibility lol.
Code:
There was a problem downloading the file scala-library.jar automatically. Perhaps you have an environment without internet access. You will need to download the file manually or restart and let it try again
