[Gretl-users] gretl.pid: No such file or directory

Hello everyone, I've come across an error while using the RE estimator for panel data and I couldn't find an answer anywhere on the internet. I've seen a similar error reported before in this list but was related to GARCH. The situation is as follows: - An unbalanced panel of 455 observations - 1 dependent variable - 9 independent variables (3 of them are time-invariant) When using a linear-linear, lin-log or log-lin, specification everything runs well. When using a log-log specification, both pooled OLS, FE and RE returns the same error window: Couldn't create directory 'D:\<...>\AppData\Roaming\gretl\gretl.pid: No such file or directory C:\Users\<...>\AppData\Roaming\gretl\gretl.pid: No such file or directory I didn't saw any reference to this in sourceforge bug tracker, so I'm inclined to think that I'm overlooking something. Thanks in advance for the help, Marcelo Duarte
