Reference Data access error

I have a SImatic S7 proyect using FC blocks for programming. When trying to
view the reference data the following message appears:

"Display (567:26)       Internal Error. Unable to set up the connection
between the two objects"

Also when tying to see the coss-reference data of any variable (right-click ->
Go to -> Location) there's another error message:

"Location (30:515)     Unable to find the reference data requested for
execution "

Finally i tried to save my proyect with another name using the option "With
reorganization" and appeared another error: 

"wcf_prox       Utah-SOM-Error ! File SOMObject.cpp, Line:1443 Text: Exception calling utah" (image attached)



Any help is appreciated

Try jklm offer - copy project into new one part by part. To be more detailed

1) HW Konfig can be copied through "export" feature and them reimported into new project.

2) Symbol table can be copied in/from excel using copy/paste

3) Instead of copying blocks i would suggest open one block (any), then File->Generate source->All blocks. After that you will get plain text that can be inserted into new project (via copy/paste), and, after compiling this source, would produce all blocks.
