Help RESOLVE Error! LoadExternalBlockFile: Deserialize or I/O error Bitcoin Code Error

Need an EXPERT DEV to help resolve issue.

Trying to do is trying to add merged mining (AuxPow) to a code base used by bitcoin/litecoin.

However, we are running into the following error:

>> LoadExternalBlockFile: Deserialize or I/O error - Read attempted past buffer limit: iostream error

This error comes from:

>> streams.h, near line 626 in the "read" method of CBufferedFile.

When trying to read a block with AuxPow, the relevant local variables in "read" are:

>> nsize 32, nReadPos 755, nReadLimit 776

The code base where most of the changes happen related to this happen in block.h:

/** Nodes collect new transactions into a block, hash them into a hash tree,

* requirements. When they solve the proof-of-work, they broadcast the block

* to everyone and the block is added to the block chain. The first transaction

* in the block is a special one that creates a new coin owned by the creator

* of the block.
