Im my 10 years using IDA Pro this never happend.
I saved using IDA Pro 7.7 when I go to open today I find out that IDA PRO didnt put header on file
If I try to open says "File .... is not an IDA database" for obvious reasons.
If I edit the header and add first 15 bytes from other database "49 44 41 32 00 00 FC 00 00 00 00 00 00 00 05" IDA opens the file and starts unpacking but then I get error "bTree error: bad B-tree header"
Its possible to recover or rebuild the header?
