FWIW - Status Report for those also operating off W7 32&64 OS.................
Am still running fine
after updating from Calibre 64 v2.8 to 2.9 with iOSRA 1.4.4 & Marvin XD 1.2.4 Plugs
AND ShellShock's 64 bit DLL replacements connecting to iPad retina with iOS 8.2.
My
updated book collection on both iPad & W7 64 Calibre v2.9 is now at 2,248
without a return of the "Malformed DB ....." 'monkey-wrench' exception. Hopefully this continues!
In the event the 'monkey-wrench returns', I expect to restore to "normal" and up-to-date operation within minutes per my prior post #75.
Regards to ShellShock
and his continuing efforts!.
