USB U2 Not programming ?

Any body knows please Help:
PS: My first languish is German
typing on a German keyboard

I have installed :

PBP #3 Gold
Micro Code Studio Plus V
Compiler V PBPX

Programmer : USB U2 melabs 4.5. Firmware 5.9
Chip Target info ID 09A4 (16F877)

My problem started when I tried to program PIC16F88.

So I went back to BASICs:
I use the USB U2 melabs with a LAB-X2 from meLAB
Chip is 16F877-20/P .
Yes power is supplied to the LAB-X2
My programmer gets power from a powered USB Port

My program is blink3x2 from meLAB sample library for the LAB-X2

When I go [program compile inMicro Code Studio] it appears every thing is fine however
the red programming LED on the U2 Programmer is not flashing !
And I don’t get the desired results on the LAB-X2

When I program from the meLAB Programmer it appears to program just
fine [the red led is flashing].unfortunate I don’t get the desired results on the LAB-X2.
Except now the hex code is changed !
