Greetings, thanks for the enquiry.
The files in question are inside the b4xlib. Have opened it in my pc and all is well.
However, I have just downloaded the file from github, for whatever reason, it corrupted, I will re-upload to gibhub/google drive.
Also, when you check, please open the dist.b4a project from your download, if everything is well, just check if any of the libraries listed show a '00" version number as at times the IDE library registration reports such errors when something goes wrong.
