I eventually had a blue screen crash in Windows 7 pro 64. I thought it might be a file problem so I restored from an earlier backup and then lost sync with the one I had uploaded. I was unable to upload again without it stalling on a sync error. I re-installed the program, deleted the online file, renamed my local family file, removed all media, compacted it and then continued to get the same sync error halt when trying to upload. I also disabled my firewall and AV software. I was able to upload a gedcom without syncing, but it replaced all European characters with question marks - unacceptable for me to use since all my ancestors are from Norway and Sweden. My family file is about 34,000 people.
I'm so disgusted with this version that I want my money back. I tried to call Nova Development for a refund but the phone wait is ridiculously long. I guess I'm not alone.
