plz let me know if u r opening the files directly from that system on which these were originally made

also if u have copied them what method did u followed?

this problem occurs when u dont have tollbox installed on the server.

but in ur case u say u have the simplfied version on ur machine.

try a thing

open the assy in that system in which tool box is thr.

the n go to file>find references

the n click the option copy files, u may get a msg that do u want to preserve directory structure. i feel u cna click no.

the n copy the entire assy to a new location and the n move that folder to ur machine

now open on ur machine and check if the same error is thr

hope it work for u

regards
