Brought a bargin MCP buttttttt..

As the topic suggests I have brought a MCP of a guy off the net that came with all the software to run it EXCEPT that its in Chinese lol

The MCP is from "sino fsx" and after using google translate and various bits and pieces Ive actually got the thing to work exceptionally well with the Level D 767 and the default 737..

Here's where the "but" starts,

When selecting the PMDG 737 all the values on the mcp are right and line up with that in the sim (fsx)

As soon as the aircraft starts moving all the values on the MCP its self reset to zero and the speed indicator back to 100kts

The toggle switches only preform an "on" function and everything pretty much turns to dust,

Im running win7

Like I mentioned the LevelD works fine but not so good with the PMDG 738

Any help would greatly be appreciated
