Hey, Im new to the forum and want to ask, whats wrong with steam? I keep getting Steam.exe(main exception):CmultiFieldBlob(pSerialized). I cant access steam at all. Help please?
Try deleting ClientRegistry.blob from your Steam directory (Typically located in C:\program files\steam) then reopen Steam. Should work. All your games will have the default settings (names, sprays, and whatnot) but you can change them back.
See if that helps.
(Also, Google is your friend.)
Ok, thanks its working now.
clientregistry.blob solves so many steam problems
