Mecabricks is working fine for me. Can't help you with your error, I'll leave that to Scrubs...

Hm... ok Thank you though!

P.S. to my original post, I think it might have something to do with the post by zachfox19 on 6 Feb 2020, 04:48.

Addition to original post.
Scrubs, since one of the models was created by you, maybe you can help. I want to download 10224-1: Town Hall using the method used in the tutorial mentioned above. Surprisingly, a few moments ago I was going to try to download it one last time and I was able to get the set to open in the 3-D view on meckabricks.com. But the moment I tried going into Editor, the error popped up again: "Error: End of data reached (data length = 0, asked index = 4). Corrupted zip ?" Any help Scrubs? Thank you so much. I'll be going off until Mon so if I don't reply to anything before then... Thanks so much again! - Yacove

The model is opening fine for me in the player and the workshop. Just post your browser and operating system here.
I cannot really do much more.

Thank you for the help. It's opening just fine now today. I have no clue what my problem was. Maybe the site was just having connectivity problems at the time I was looking. Thank you so much again Scrubs! - Yacove
