lvds with max10 eval board

I am trying to interface ADC (LTC2264) to max10 via LVDS interface. The ADC provides clock, frame and serial data, all as LVDS signals. I need just to interface LVDS to max10, then sample the data; no PLL necessary

When I define a single pair as LVDS (e.g. DIFFIO_R14P_CLK2P/N) in the assignment editor, the compilation stops with message "Sorry The QuartusII software quit unexpectedly"; the last message

"Warning (171167): Found invalid Fitter assignments. See the Ignored Assignments panel in the Fitter Compilation Report for more information". Because of the compilation crash there is no Ignored Assignments panel in the report. Details of the crash are shown below.

Before the LVDS definition of the pair the project compiles and works correctly.

Any help is greatly appreciated.

Thank you,

Vitaly
