Thanks jcl, but I don't believe the VPS is the problem. I have further done the following:

On a completely different computer I have done a fresh install of 1.40.2. I have on this computer run Download on the Z12 account with no problem to verify the install. On this computer running Download on the Z3 account fails as follows (quite different from how 1.34.1 fails, but still failing):

"Login FXCM" prints in the window followed by 2 dots, then nothing. I have waited up to 1 hour to verify nothing further happens. Stop is still available so I click it. Then "!Can't open tables!" and "Can't connect!" are printed. At least this Zorro version doesn't hang completely. diag.txt contains:

Does this help to identify the problem?

Thanks.
