You probably won't believe this:
I uninstalled Calibre through the Control Panel options. Re-downloaded 4.129. Installed 4.129. Opened Calibre, and GOT THE SAVE VERSION!! Still says "4.121 . . . Latest version: 0.4.128" on the upper right.

So I repeated the steps. This time after uninstalling I closed out Control Panel, returned, and verified that the program is no longer listed in the Add or Remove Programs folder. Went to the c: drive and saw that there is a Calibre folder under the c:\Programs. Tried to delete the folder but got an error message saying I can't delete it.

So I thought maybe I should leave it alone. Reinstalled 4.129. Same result.
Some creature is in my computer!! I'm sorry to continue to bother you about this, but do you have another suggestion? I loved your program and I want to use it again.
