Hi,

I have some problems do not how to solve. 
I received messages after CONN is launched via the trial version MATLAB_2021a with spm12 and conn20b
The message shown in Matlab after launching is as follows.

ERROR DESCRIPTION:

While the message shown in CONN is about [ "spm_unlink.mexmaci64" cannot be opened because the developer cannot be verified ] and asked to be removed attached as file "1". I ignored and kept the file.

Still no fMRI image is shown.
Please advice. Appreciated.
