I tried to open a Print Master newspaper file that was corrupted by a accidental external disk format. The file was recovery isn’t working. is there any way to repair these .nws and .sig files?
Maybe try running the fix discussed here: http://support.encore.com/technicalsupport/kb.aspx?kb_id=1526&product_id=2832. It will fix the Pritnshop database with a downloadable app. That may allow the program to work again.
there should be some companies that can handle this difficult task, if files are important then perhaps to try them and ask fees
