"No importable cards were found error."
Operating v.10.8.3. Using contacts to import a .vcf (v. 2.1) file, sent to the download folder. Done it dozens of times before, prior to v.10.8.3. In the past, no problems. Now I get the "No importable cards were found error." Have tested it with 6 different .vcf downlaods, all v.2.1...same error message. Any suggestions?
