wybuild after system reinstall

Hi,

i forgot to copy my save from wybuild before reinstaling my os. now when i wanna do new update im uploading it in to the same folder on ftp, aplication downloads update but then the red X comes out with error :

The downloaded file "srp.all.to.1.51.wyu" failed the signature validation: Verification failed.

This error is likely caused by a download that ended prematurely. Total size of the downloaded file: 377,78 KB (386844 bytes).

Computed SHA1 hash of the downloaded file: AB-DA-B5-B0-52-C2-D3-95-7D-76-1A-C9-2F-03-8E-16-CD-35-0C-54

what to do?

You mean you forgot to save your wyBuild project file? If that's the case, and you can't recover it, then you need to distribute new client.wyc files to your users before they can update. The reason this is the case is that wyBuild uses signed updates (see: Signing Updates in wyBuild).

In other words, your new updates are signed with a key that's different than the key of your old wyBuild project. Thus, wyUpdate is rejecting the update.

Does this make sense?
