Invalid time string specified

Hello, I am currently having a problem with ModelSim 10.1d.

I load in a project, and all of the files compile. Whenever I attempt to start simulating a project the following error occurs: Invalid time string specified: 1000. The window for the waveform is showing up as a blank grey background.

I have tried to change the time in the transcript terminal by using the running command. I have also re-installed ModelSim and Quartus II. I've deleted the entire directory and .ini file. However, this issue keeps popping back up. Older previous projects that have simulated with no issues in the past are also causing problems. I have also checked all of the projects by running them on another computer, and I do not have the issue.

I'm running out of ideas to try and was hoping someone else might have one.

Thanks in advance!

    You'll need to post the code where this time string exists.

    How address your loading the project? Are you trying to launch the simulation from quartus?

    Hi Tricky thx for your quickly answering

    I can't follow the word "time string exists" does it means the time when the first output shows up?

    and I'v never launch from quartus because when I compile the project , the qurtus tells

    "Error (10533): VHDL Wait Statement error at gx_tb.vhd(64): Wait Statement must contain condition clause with UNTIL keyword"

    I thougt VHDL can't compile the "wait for", i was also confused about it !

    It looks like you're trying to compile a testbench in quartus. You can't do that. Test benches can only be compiled in simulators
