problem with new update

[Rass]

Dear Pablo after upadating to 15.2.3, WB doesn't open any project already created with 15.2.2 version. My OS is the latest Windows.

[Pablo]

Version 15.2.3 is just a minor update compared to 15.2.2, there were no changes to the file format.
If there an error?
Can you please be more specific?
Do you have an example project?

[Rass]

Thanks Pablo, yes, there is an error saying: "JUSTIFIEDGALLERY" could not be loaded. I have already reinstalled the referred extension. Then, there is another message: "Make sure you install the same application or newer as the one used to create the project

[Rass]

Where should I send you an example of the project?

Download the correct version? (64bit or 32bit)

[Rass]

Tnanks for your kind answer, I have tried both versions

[jerryco]

Of the application or of the extension?

[Pablo]

This error indicates that you did not install the 'justified gallery' extension. it's unrelated to the update.
Maybe you have installed the 64bit version but did not update the extension to 64 bit?

[Rass]

Sending you the created project

Are you opening the project from within WebBuilder, or double clicking a web builder file?
