I have several class libraries originally written in VFP 3.0 and is still being used in my VFP 3.0 applications. One time, while trying to find out about the alleged speed improvement in VFP 5.0, I tried to run my old application, all the libraries were recompiled by V5 and when I went back to them in V3, I got "...compiled in previous version of VFP..." error.

Now I can no longer work on my old applications because of this. Can anybody give me some help on how I can revert the libraries to their older version?

Thanks in advance.
