First, I'm using BT to sync between 2 of my own PC's (saves schlepping a laptop around). I "manually" setup several devices (copied same root files to each device) and then setup BitTorrent on each. After several days of modifying files on various machines, I noticed I've got about 100 files on 1 PC that have somehow ended up being BTS placeholders! None of these are files I've modified since the original setup. Worse yet, on the other PC, about 50% of the files are now BTS placeholders, INCLUDING the 100 that are BTS on the other PC - Where did the original file go???? BitTorrent is acting as if everything is synced. I manually try to open/sync the BTS placeholder, and I get an error "XXX file already in Queue". There's no rhyme or reason to which files are placeholders; in some cases, and entire folder is BTS, in others some (or most) of the files in a directory, but not others. Some folders have all the files. I've appeared to have lost the 100 originals from the one PC (I can restore from a backup, but I don't want to do that until I figure out whats causing this problem). In some cases, I'm going to have to restore from the backup, which is about 2 weeks old. In most cases, I'm going to have to manually compare last modified dates to restore my originals. Help! Windows 7 x64 (on both PC's), Free version on both, setup with Pro trial. Pro trial has expired on one, but not the other. Both PC's setup with OWNER and SYNC ALL. Devices setup with Sync on 6 folders. The folder drive is encrypted (DiskCryptor) on one PC, not on the other (yet). Unencrypted drvie on 2nd PC is receiving files through BT with no encryption issues. I thought I'd have issues because the 2nd PC's drive hasn't been encrypted yet, but the files that are syncing appear to be "arriving" and "sending" correctly.
