Known Issues with CryptoSys PKI Pro

The VBA x509QueryCert helper function in the file basCrPKI.bas has an error at line 4658.

ORIGINAL:
    If n <= 0 Then Exit Function
    x509QueryCert = CStr(n)
REVISED:
    If n < 0 Then Exit Function
    x509QueryCert = CStr(n)

When the return type is an integer and the result n is zero, then the string "0" should be returned, not the empty string. Thanks to Tim Carter for pointing this out.
