[Cmpl] cmpl error: Can not read the solution

[Mike Steglich]

Hi Matthew,

I tested it under Win64 and unfortunately I can't reproduce the problem. Could you run this model with the command line argument -dontRemoveTmpFiles and send me the files  <filename>.cmpl,  <filename>.osil and  <filename>.osrl. Please send also Cmpl's stdout.  It would be also helpful to have some information about the system you use.

Sorry for the trouble.

Thanks,
Mike
