Error al abrir proyexto (Error opening proyexto)

I lose pictures

please help



Several possible issues here Carlos.

You may be experiencing the server issue that is described with the Red message that shows up on the AI2 pop up start screen.   Please read that.  The MIT statement is also here: https://docs.google.com/document/d/1wQy_1uCsZDAXY51wElbMyfy8AJid_EOqklIX_ggzBJY/pub        This issue affects people using lots of images in their Media folder and it might also be text.  There are temporary ways to get the blocks to run if you peruse the posts for the past few days, however, MIT hopes to have a fix soon.

It has been suggested that you might delete all your Media images, then reload them and try again.  This reportedly works sometimes but then later pictures disappear again and that will happen until MIT fix the issue.  This server issue apparently is not affecting projects that do not have images etc. in the Media.

Watch for the color of the message in the App Inventor splash screen to change from RED to another color or monitor this forum.   Yes, for the moment, AI2 is broken for some users...sorry.

MIT App Inventor still has issues with the Google Cloud Storage, as mentioned in the red splash screen which results in missing assets, see also here https://docs.google.com/document/d/1wQy_1uCsZDAXY51wElbMyfy8AJid_EOqklIX_ggzBJY/pub

What you can do meanwhile is 

1. wait until these issues are fixed, or

2. install a personal server and work completely offline. 

Krupong just updated AI2U, version 2.3 is now identical to the MIT App Inventor version nb139c as of Dec 13. Just download the 32 or 64 bit version here http://sourceforge.net/projects/ai2u/files/ai2u%202.3/, install it, start AI2U and your own personal server is up and running! Then just open your browser using the address http://localhost:8888 . That's all.

And btw. with your own personal server you also will be able to build projects larger than 5 MB. So what are you waiting for?
