So, after that i try to google, i find some suggestion that i copy the whole folder in my laptop to the new pc, and i try that i just can log in using investor mode only... can anybody help me on this, btw my account is ibfx.
thanks

anyhelp would really be appreciate...

What does it say in the Journal tab when you try log in normally?

if say invalid account..but i can log in from my laptop normally..any ideas about this?

Yeah, your password on your PC is incorrect. Invalid account is either an expired demo account or it is an account number/password mismatch.

The fact that you can log in as an investor or as a trader from another computer tells me the password is incorrect and not an expired account.

do u have any suggestion what should i do, if that i should change the password on my laptop?

Is it a demo account?

If so, just log in on your laptop, go to the mailbox tab of the terminal and get your password out of the mail that you would have received when you created the account. Then use that to log in via your pc.
