We tried a few different ones, all of them in text expander (pretty simple things - example ".pnz" and the substitute "Thank you for your time". And the error code says it is not a valid key name and some numbers. Will try to send the other details on your email. Thanks in advance.

Hello,

When saving a string, a few people in the office get error code. The strange part is that this happens only to a few people, for the others works fine. We tried to reinstall and install again (a few times) but was not helping. Any suggestions?
