For the KPOINTS given belowI have calculated wirh vasp5.2 the eigenalues usind LDA + u without any problems. Then I switched t0 HSE ussing the preconverged CHGCAR and WAVECAR. But I get always the follwoing error:
internal error in FOCK_ACC: number of k-points incorrect 8
8 2 2 2
internal error in FOCK_ACC: number of k-points incorrect 8
8 2 2 2
internal error in FOCK_ACC: number of k-points incorrect 8
8 2 2 2
Below I send the POSCAR file, KPOINT and the two INCAR files.

Hmm, it looks like there are different k-point sets around. Maybe there is a different treatment of the k-mesh in DFT(+U) and hybrid calculations?!
I'm not sure if the following would work: Take the k-point set from the HSE OUTCAR (somewhere at the beginning) and modify the KPOINTS file of your LDA+U calculation accordingly. You have to convince VASP to calculate with the HSE kpoint set.
Again, just my guess.

This has been addressed by admin in the HSE band structure thread: remove NKRED = 2
