As the backuptool starts to calculate the disk space required for the backup I get "Omgbkup.exe has encountered a problem and needs to close. We are sorry for the inconvenience." Event viewer reveals Faulting application omgbkup.exe, version 4.3.1.14020, faulting module msvcr71.dll, version 7.10.3052.4, fault address 0x00010440. I've tried re-installing SS 4.3 and msvcr71.dll. As I've been using Omgbkup for the last 3-yrs with no problem I'm assuming my PC has somehow been corrupted. I'll be grateful for any thoughts.........
