LVP read as OFF by IPE,but it is ON actually in PIC16F1459

I think this question has beed mentioned at: http://www.microchip.com/forums/m1033870.aspx
here is a detailed description:
yesterday and for months time,i used IPE3.65,PicKit3,PIC16F1459,for LVP flashing;
IPE3.65 setting:
selected: "use low voltage programming mode entry" and "power target circuit from tool"
VDD set is 3.3V
PIC16F1459 setting:
LVP = ON
wiring:
RA0/RA1 as PGD/PGC

and they did work;

today i upgrated to IPE 4.10,settings are all the same include hard wiring,but 4.10 report below errors:
"
MPLAB X has detected that the device’s low voltage configuration bit is set to OFF but the tool is set to low voltage programming and cannot program the device. To correct this:
1. Change the tool’s programming option to use High Voltage programming.
2. Change the device’s configuration bit to use low voltage (LVP=ON). Program the device using high voltage to reprogram the device’s configuration bit.
3. Change the tool’s programming option back to Low Voltage programming for subsequent programming of the device.
"

i did flash via RC0/RC1 with Changing the tool’s programming option to use High Voltage programming;and keep PIC's LVP = ON;flash successeded;but still get the same error when return back operating at low voltage as mentioned at above No.3.

i am afraid that IPE4.10 is wrongly reading the PIC16F1459's configuration bits,since same settings worked on IPE3.65;PIC's LVP was set ON ,but IPE4.10 read as OFF,why?

    Older versions didn't check for the LVP bit. It's something new. I suggest you file the support ticket.

    Go to http://microchip.com/support
    (you will actually end up at http://www.microchip.com/support/hottopics.aspx )
     
    That is where you do it. the very first help topic there is "How to submit a technical support case?"

    Hi uzsim,
    I got your case number.  Unfortunately I cannot duplicate this.  I'll grab your case and hopefully you can help me duplicate it.
     
    Thanks,

    Hi Howard,
    I just tried closing the case but failed when click the "......../Close Case";
    i will try later;
    Could you kindly advise where i can download IPE4.01? i just found only the most new version 4.10 is availabe on microchip.com

    Thanks!
