[EpiData-list] Access violation message- unable to open database

I am in the middle of creating a database
on Epidata Manager v2.0.5.51 for Mac. There is one dataform and no
databases. There are 13 sections and 468 fields so far. 


Today when I tried to open the database I
get the message: 

“The file [xxxx] is locked by another
program! The file was locked at [last time I tried to open it] by [my

Continue opening this file?”


If I say No, the box just closes. If I say
Yes, the database opens in the background but I get the message:

“Access violation.

Press OK to ignore and risk data

Press Cancel to kill the program”.


I have tried pressing OK many times but I
can’t get beyond the error message and can’t access the database which I
see behind it. I can see that I haven't lost any sections of the
database since I last saved it last night.

If I press Cancel then Epidata Manager
shuts down.


I’ve been through this process many times.
I can open the database on Epidata EntryClient. I can open other
databases on
Manager with no problem. 


I have tried opening the ‘problem’ database
in the latest version of Manager on a PC but it also doesn’t work. I
downloaded the software again but that doesn’t work. I’ve restarted my


Any advice on how to open this database
again would be very gratefully received. I can’t see any relevant
entries on
this particular scenario in the archives.


Kind regards
