Maarten,
   The error message suggests that it isn't the number of equations that 
is the problem but the number of operators in your equations that is 
limiting you. I've never run into this before! It is strange that the 
model was working previously and having deleted some equations does not 
anymore; I suspect that it might be a bad error message due to some 
other problem and would recommend that you send your input file to your 
distributor for them to have a look.
Best,
  David
