Framework Upped to 4.8 fixes the TLS issue the client is having?

tbh I have no clue why an older version also fixes this but it seems this also does the trick?
also, a newer framework version doesn't hurt.

For me this issue seems to be fixed.
#41 #42 fixes those two problems cause they are the same.

The problem with #41 and #42 is a failed check for an invalid input in the checkForUpdates method. I do not know why this would fix the problem but seems like a good idea to update the framework if compatible anyways.

seemed weird for me too,
the invalid input comes because the webrequest returns null
Since the TLS check fails. (Can't get a secure connection for whatever reason)
which then crashes the program (could've also added a check for the potential null but seems to work like this soo?)
