WT3 Problem

[ultrabozobass]

I have bought the WT3 before 1 and a half year.I did some measurements at first and as far as i remember it was working OK.For some reason i quit using it and left the unit with resistor in box for over a year on the shelf.
Recently i tried to take some measurements again on the same PC.I run Windows XP SP2.The calibration was showing completely weird measurements and always different from previous.The resistor was 1K and it was showing everything under 500 Ohms.Also completely crazy values for TS parameters.
I tried to install the program to a different PC with Windows XP SP2 for the first time.I have the same problems plus that when i try to measure TS i see only Le.Everything else is zero !!!I don't understand.It's the first time i install this program in this PC.I restarted the PC waited for minutes to stabilize but still the same problem...
Also at Test Leads Calibration it reads values around 100 to 130 Ohms.
