Issues with installing BCILAB on MATLAB

I followed the Quick Start Guide by SCCN to download BCILAB. Yet the installation message has too many warnings (compared with their demo installation, which was errorless/warning-free). I think the warnings are responsible for two things:

1. BCILAB GUI toolbox not showing (although it appears to be an active window in the Windows task bar at the bottom) 
2. A data loading error that appears when I try to train data in BCILAB (using shortcuts instead of the absent GUI)

I tried to solve it by changing folder locations, however the warnings only rearranged in order. 

Here is the list of warnings:

Warning: Function cummax has the same name as a MATLAB builtin. We suggest you rename the function to avoid a potential name conflict. In path (line 109) In addpath (line 88) In env_load_dependencies>load_dependencies (line 165) In env_load_dependencies (line 78) In env_startup (line 224) In bcilab (line 115) 

The above warning appears 6 times.

Warning: could not access the local eeg_options file eeglab: options file is C:\Program Files\BCILAB-master\dependencies\eeglab_10_0_1_0x\functions\adminfunc\eeg_options.m

Warning: A value of class "com.sun.management.OperatingSystem" was indexed with no subscripts specified. Currently the result of this operation is the indexed value itself, but in a future release, it will be an error. In hlp_memfree (line 18) In env_startup (line 347) In bcilab (line 115) 

And an error: 

Error running dependency loader C:\Program Files\BCILAB-master\dependencies\eeglab_10_0_1_0x\env_exec.m; reason: While setting the 'FontName' property of 'UIControl': String value must not be empty The dependency will likely not be fully operational.

Is it indeed a problem of paths? How can I solve this?
