You must have made some other change in addition to using a new filename when you started your new file.
No suitable back end error usually means that the data file is not in the expected format. Gnucash expects an xml-like format or certain database formats. Database formats need corresponding database programs to read them. Read the FAQ about files for more info. If this doesn't help come back with more details about the file format you thought you were using, whether you are storing files in a different folder and anything else that may seem significant.
