Hmmm, your topic says "Mathcad Prime 6.0" but in your text you write Mathcad 10 ????
Even if you are using a trial license you can convert the files yourself during the trial period of 30 days. But you have to explicitly check the option to install the converter when you install Prime. If you forgot to do so, you can simply run the installer again.
After the trial period Prime falls back to a crippled version called Prime Express. It can read all Prime files but will refuse to use "premium" features. Converting legacy is such a feature. Its also very likely that because of this the converted files won't run OK in Prime express if the use features like programming or symbolics which are not supported by Prime Express.
Anyway, if you are not able to convert the files yourself, you may post them here and maybe someone will be willing and able to do the conversion for you. You sure will have to clearly state for which version of Prime you need the files converted to as Prime 6 would not be able to read a Prime 10 file.
