I removed dropbox syncing from an older laptop a while back because the laptop couldn't handle the file size. Today I reinstalled dropbox on that machine hoping to set it to online only so it wouldn't take up hard drive space. As soon as it installed it starting syncing and I noticed the files were not the same as on my main machine. I'm not sure what blueprint/main files it's pulling from. I checked dropbox online and on my phone and the files are now the same as they show on the old laptop (with TONS of files missing). I checked on my desktop and they looked like the original, but I immediately stopped syncing for fear it would update there too. There are hundreds of files missing and I have no idea what happened or where it's even pulling from. The laptop sync should be pulling from what's online, but it appears the online and phone version updated to what's on the laptop.
How do I fix this? I fear I've just lost all these files for good.
