This indicates that it is trying to run the READ module (Lanczos) at line 159 in subDMAP XREAD. Looking at the DMAP listing (obtained by adding COMPILE XREAD, LIST just before the CEND), line 159 is:
your error says that the input datablock in position 11 does not exist - that is INVEC (or if you look at the DMAP module dictionary, EQMAP - Table of degree-of-freedom global-to-local maps for domain decomposition. Required only for geometric domain decomp.
At this point, I would say the best thing is to directly contact MSC support and send them the input file, so they can try to determine what the problem is.
In the meantime, you might try Sanjay's suggestion or mine (troubleshoot the model).
As I stated, massless mechanisms are an indication of a modeling problem - my personal opinion is that if they exist, there is a potential major problem in the model and you should try to determine where they are and correct the modeling errors. The best way to do this is to try running statics first and troubleshooting those runs.
