Just converted a pretty old (parts might have been written in VDF 4 or 5!!! - I honestly can't remember) system to DF25.

It converts OK from the DF24.0 vesion, but on opening a project (any project it seem like) in the converted workspace I get a series of errors in the Studio:

Code:
C:\Program Files\DataFlex 25.0\Bin64\Studio.exe
Invalid message GET_DDREQUIREDCLIENTS


Error: 98


Please report this error to Data Access Corporation

After clicking "OK" on about 4 of those those it comes up fine and compiles and runs OK AFAICS, so I'm just letting you know as requested. There is no "Debug" type option and I can't find the message doing a quick search, so I'm not clear what might be causing it - as I say, parts are very old!
