Java virtual machine launcher error could not open file

Can I contact someone to get technical help? I have used vassal for years but yesterday I got the following error messages when I tried to open modules:

the application requires a Java runtime environment

the pipe has been ended

Java virtual machine launcher error could not open file

  • What OS are you using?
  • What version of Vassal are you running?
  • What is in the errorLog after you have the problem?
