Machine specs: HP Notebook - 15-ac053tx
OS: Windows 8.1 with all updates
RAM: 8 GB
GPU: Intel onboard and AMD Radeon M330
Calibre: 32 bit portable updated to latest version

Background:
New laptop so I copied my portable Calibre onto it. Then I decided to try loading the 64 bit Calibre installable but had problems with porting the library. So I uninstalled it. Since then I get this error whenever I try to load a book in the portable version. "Failed to read book." "Failed to connect to worker process."

I checked the registry and saw many references to the 64 bit version, so I reinstalled it and used Geek Uninstaller to do a full uninstall of it. I also manually cleaned the registry of all references and even copied the portable version again after deleting it from the hard drive. Still the same issue.

Really would appreciate some help on this. Is there some way to reset the library or something?
