Navlink Opening of project

[Altera_Forum]

When using Tools>Run Simulation Tool>Run RTL or Run Gate Level, shouldn't Modelsim automatically open the project with all project files listed in library tab?

Additional question: What is the cause of compiler warning 275014: INPUTC, OUTPUTC and BIDIRC pins not supported for pin "_____". Altera help is not clear on this.

This error is listed for all inputs and outputs of a BDF block that previously had no such errors when compiled in Quartus version 13.0. The block only has two component types, 8 adders and 8 FF's that were generated lpm functions. This occurs in both 14.0 and 15.0 versions. Should I update these lpm blocks using FILE>CREATE UPDATE>CREATE HD DESIGN FILE FROM CURRENT FILE or update vhdl files. Don't understand why they are now incompatible if they haven't changed.

I guess nobody knows anything about the source of is error. Seems that new versions of Quartus are not compatible with older, especially lpm functions. Many posts about this issue.
