restore database error

[cilembub]

I have a 400 MB database backup, and when I tried to restore it it said

Error: dbbackup failed: Unable to restore database 'xxxxxx'
Exception of type 'System.OutOfMemoryException' was thrown.

so I thought it was to big for a quadcore with 8 GB of RAM??

then I tried searching ways to open the backup data so I could extract it, but no joy, tried to rename to zip but it wont unzip, to rar it wont unrar.

I'm desparate. Any help?
