Fix broken or corrupted files

Hi there! I'm super stressed because my  project stop working.
When I try to preview it, the content doesn't load.  When I do a slide preview, it works, also with a scene preview... but it doesn't work for a project preview.
And it happen the same when I upload it in moodle, no matter how I export it.
I attached some screen prints and the file itself.

Can some one help me?

Hi Eli! Sorry to hear that you had difficulty with this, but the 'why' when it comes to corruption is a difficult one to answer.

We do have some basic tips:

File corruption is unpredictable, and there's no straightforward way to determine what causes it. Common causes are environmental (disk errors, power outages, improper shutdowns), viruses, failed Windows updates, and even file size (i.e., very large files have a higher risk of corrupting).

Consider these preventative measures to protect your project files:

1) Save and publish projects on your local hard drive. Working on a network drive or external USB drive can cause erratic behavior due to latency.

2) Save incrementally. If your app has an AutoRecovery feature, take advantage of it. If not, save a new version of your project every hour or so with a new file name each time. If a file becomes corrupt, you'll still have a working version available.

3) Install Dropbox. Snapshots of changes in your local Dropbox folder are kept for 30 days. If a file is damaged or deleted, you can restore a previous snapshot:

4) Don't leave the app open and unattended for long periods of time. Some users have reported file corruption after leaving their apps open overnight. It's possible that a malware scan or disk backup could run because the machine is idle, making your app vulnerable to crashing.

Did adding in a new result slide or re-creating the question bank help you out?

Hi Eli,

I'm sorry this file is giving you so much trouble, and you've definitely come to the right place. It sounds like you've made some changes to your file and now all the gifs are broken and the seekbar won't work, is that correct?
