MACHINE LOADS RPRO AND FREEZES BOX APPEARS BEHIND RPRO

Worrked with mission beauty, 1 machine wouldnt go into RPRO with out freezing. Renamed the WS folder no luck changed the WS parameter on the RPRO shortcut worked fine. when loading RPRO we could see a box appearing behind RPRO but becasue it freezes you cant access the message. Pressing ALT SHIFT brought the box to the front of the screen it was a range check error on file 1ESPI5VDVF.PBK. this was a securedoc file in the securedoc>ws5>rc200601 folder. I did a search and found the file. deleted worked fine
