So I've checked the Dictionary lookup XML file and that password works to log in via the website. This was also working last week but stopped at some point over the last week. I've got cTAKES running on a linux system so I can index batches of documents via a script. The exact error is as follows (with the username/password blocked out).

Initialization of CAS Processor with name "AggregatePlaintextFastUMLSProcessor" failed. I also have a test implementation on a local windows 8 laptop that also fails now due to the same error so it seems like it's UMLS related issue but I haven't heard back from them yet and was hoping perhaps someone with cTAKES has previously experienced and resolved the issue. Thanks!
