Please check the permissions of your gallery folder and all files and subfolders within it to ensure that they are not restricted or read-only.
One possible workaround would be to re-save your gallery to a new empty folder (instead of re-saving to the same folder) and then delete the original gallery folder afterwards.
If the problem lies somewhere within svBuilder-Pro, then maybe a completely clean install will help.
Please try the following to make sure that there are no files left behind from a previous svBuilder-Pro installation before reinstalling the application. I realise that you may already have tried the procedure before but if there is absolutely no trace of svBuilder-Pro on your system before re-installing the application (and there are no issues with folder permissions), then it should work fine.
(1) Uninstall svBuilder-Pro.
Mac: Delete the 'svBuilder-Pro' file from the Applications folder and empty your Trash.
Windows: Use the uninstaller in the 'Control Panel -> Programs -> Uninstall a program...' list.
(2) After uninstalling svBuilder-Pro, please check that there are no files are left behind by manually deleting the following folders from your hard drive (if they exist):
Mac: /Users/your_username/Library/Application Support/Adobe/AIR/ELS/svBuilder-Pro
Windows: C:\Program Files (x86)\svBuilder-Pro
Windows: C:\Users\your_username\My Documents\svBuilder-Pro
You may need to show hidden files to find some of the above locations in Windows Explorer: http://windows.microsoft.com/en-gb/wind … dden-files
(3) Next, search your hard drive for the term 'svBuilder-Pro' and delete any and all entries found (to be absolutely sure that nothing remains).
(4) Also, please follow the procedure above (Steps #1 - #3) for svBuilder, too.
svBuilder and svBuilder-Pro can both be installed and run side by side on the same computer but, being that you are experiencing problems, it might be wise to completely clear your system of all svBuilder files before trying to reinstall svBuilder-Pro.
(5) Then re-install svBuilder-Pro following the instructions here.
I do not know if this will help but it is certainly worth trying.
