Bitdefender automatically blocked a load of files related to NoteCaddy in HM3, now it's also blocked one in HM2 - thirtytwobitipc.exe.
I'm sure these are false positives, but thought I'd better inform you guys.
In HM3, I managed to restore Notecaddy, but it's gone again now.
Edit: HM3 is trying to redownload NoteCaddy but it's not working.
