>> Hi Folks,
>>
>> First a couple of comments about the recent problems.  If you want to 
>> skip the
>> comments, skip the next few paragraphs for the URL of the new application 
>> note.
>>
>> First of all, I was on vacation when FJ was added to the DXCC Entity 
>> list,
>> otherwise I would have released the country file sooner.  However, while 
>> not
>> straightforward, I believe that it is possible to successfully edit the 
>> country
>> file and not cause data corruption.
>>
>> Second, I work with raw country file data in text format outside the 
>> DX4WIN
>> program.  I have a special utility that Paul wrote to generate DX4WIN.CTY 
>> from
>> this raw data.  So my method of editing country file data is much 
>> different
>> than what a user would do.
>>
>> I'm sorry if people suffered data corruption while editing their country 
>> files.
>> I can't say specifically what caused the problems, but what appeared to 
>> happen
>> is that the addition of "FJ" pushed all the subsequent entities down by 
>> one,
>> thus linking United States to "JZ0" instead of "K".  Since JZ0 doesn't 
>> have
>> states, state data in the logbook may have been lost.  I can only see 
>> this as
>> being a problem if the logbook is OPEN while editing the country file, 
>> but
>> DX4WIN does not let you edit the country database unless the logbook is 
>> closed.
>> Again, this is just a theory, and I can't actually explain what happened.
>>
>> I hope this unfortunate incident has impressed on you the need for 
>> regular
>> backups.  I have previously written a long application note on DX4WIN 
>> backup
>> strategies, and I suggest you read it again:
>>
>>    http://dx4win.ad1c.us/appnotes/backup.htm
>>
>> Unfortunately, this is like closing the barn door after the horse 
>> escapes.
>>
>> If you have upgraded from another DX4WIN version in the past, it's 
>> possible
>> that you can recover some of your missing/corrupted logbook data from an
>> earlier installation of the program (look at the dates of your old .DXL 
>> files).
>> Note that there is a known import bug 7.03 which caused imported QSOs in 
>> the
>> DX4WIN# (.DXQ) format to all be marked as Invalid. There is no multiple 
>> QSO
>> operation to change these QSOs to invalid, however.  Paul is aware of the
>> problem and it should be fixed in the next version.
>>
>>
>> Today, I have written the following application note describing how to 
>> add a
>> new entity:
>>
>>    http://dx4win.ad1c.us/appnotes/entity.htm
>>
>> I would appreciate if a few people could apply these instructions to the
>> *previous* country file (that does not contain FJ) that you can download 
>> from:
>>
>>    http://www.country-files.com/dx4win/download/DX4WCTY_20071211.zip
>>
>> and let me (or the reflector) know of their experiences (i.e. did I leave 
>> out
>> any crucial steps?).
>>
>> I empathize with those of you who lost data, but there's not much I can 
>> do to
>> help you recover it.  Read the backup application note; there's a chance 
>> that
>> you may find one of DX4WIN's internal log backups from before you made 
>> the
>> country file change.  Or you might have a log from an earlier version of 
>> DX4WIN
>> that you can use to help restore the missing data.
>>
>> If you have any questions, please reply to the reflector.
