Hi all-Posted this over at Aivla but no useable solution offered yet..Installed FSX on new, larger HD. EFB became inoperable because of an "fmc_ident.txt not found" message. I was told to reinstall AIVLASOFT_1101.exe and all should be well. Watching the installation, AIVLASOFT_1101.exe installs in H:\FSX\Aivlasoft\...(my drive with FSX installed on it).Starting the Data Providerafter the above install, the path it's set to is H:\FSX\FMCWP\NavData\fmc_ident.txt which of course results in an error "fmc_ident.txt not found" It seems to me that I should be able edit the path, but I couldn't find a way to do this.Anybody have any experience with this, or how to fix it? EFB will not start without it.Thanks,Mark

Answered.(In short - copy the Navigraph files and folders from where the Navigraph installer puts them to where you have the EFB DataProvider reading them.)
