PCS500 "No hardware responce" on calibration

Hi!
[size=50](sorry for my English)[/size]

I did not use my Oscilloscope very long time. Now I need him and … him not work!
After discovering in what problem I found that not work -5VA circuit. The failure was in C10,C13,C16,C24 capacitors. I replaced them.
Now if I press Run or Single all look like good, BUT! I can’t do Calibration. Software “says” to me that no Hardware response.
I use WinXP with PCI-LPT Board on 0xE800 address.

Now I use oscilloscope without calibration. All work, BUT not calibrated.
What is wrong? Thx.

If not yet done, you can try following:
In the oscilloscope’s menu select Options > Hardware Setup.
This opens a dialog.
In the dialog click OK button.
This should start the calibration.

This way not work too. Same effect.
Once software detected hardware and calibration has done. Now my oscilloscope calibrated but not detectable. This make some discomfort, but all work.
