Problem with pipo x7 map: cannot find required map name

Hello, I'm new one here and I have a big problem by using my PipoX7. Maybe someone can help me:
I bought for 2 month ago a pipo x7. unfortunately it stops working with the following error:

EFI Shell version 2.31
Current running mode 1.1.2
map: cannot find required map name

Windows 8.1 will not boot anymore

I'm not realy a PC specialist but If anyone know how to fix this Problem and give me a step by step introducion, I will do my very best to fix the problem :-)

Sorry that my english is not well. The reason: It is not normal to speak or write the whole day in this language...

kind regards
