Hi,
Have you tried to remove the .mtx file from the map folder ?.
The following technote has details.

Recommendation to remove .MTX after a WTX upgrade, prior to opening maps
It is recommended to remove any .MTX files, prior to opening a map source file, following an upgrade of the IBM WebSphere TX Design Studio installation (be that via a patch, Service Pack or a full version install).
Symptom Random failure results may be possible if the .MTX file (which was generated with a previous version of the Design Studio) is not removed.
Cause The initial map open process fully parses and validates the schema and creates a read-only, intermediary native schema type tree (.mtx) file. Subsequent open processes retrieve the WebSphere Transformation Extender-specific information that is stored in the cached .mtx file, similar to retrieving the information from a type tree (.mtt) file. Retrieving the information from the cached .mtx file is designed to improve the response time for opening maps that reference an XML Schema. Certain structural changes of MTX file between versions, may cause incompatibilities.
Gertie.
